Argh, this is totally my bad! I had a final-fixes that was removing any mappings that didn't pass this test: if data.raw[signal.type][signal.name] then Obviously because type=tool this wasn't working because it's of type=item in the color mapping table. I guess I'll have to loop over all the differe...

Thanks Klonan. It doesn't give an error when you specify type="item" however the color mapping doesn't work. If you wire up a lamp with a science pack that has a color mapped the lamp will just glow white regardless of the color specified. I'm not sure exactly when this changed. It definit...

Previously it was possible to map lamp signal colors to science packs as the following worked: {type="item", name="automation-science-pack", color={r=0.71,g=0.05,b=0.09,a=1.00}} However as science packs are defined as "tools" this color mapping no longer works. If you c...

Just wanted to add my thanks for posting this solution. I couldn't work out why my Factorio was rendering so blurry on my 5K iMac and this was the solution. It's definitely related to Steam upgrading from 0.16 as deleting the Steam installation and re-downloading it fixes the issue.

I noticed this is now implemented in 0.17 through the gate_connection_patch property. Thanks!

Thanks, that is very helpful indeed!

Thanks!! I assume most people don't post branches like either this but there's plenty of people playing both versions of the base game at the moment to warrant it. It's really only a display issue on the portal as the game handles the correct latest file for each major Factorio build. Just getting t...

Someone post a log after a session with the issue please. Sure, here's all the details. The log file doesn't show anything unusual however I have attached an old campaign save that will reliably reproduce the issue. I performed these tests on 0.17.8. Steps to reproduce: Copy the attached save to th...

Okay, posting an update here in case anyone searches for this in future... Bilka was right and it was being caused by another mod. It wasn't easy to troubleshoot (lots of testing one by one and restarting the game) but I was ultimately able to fix the issue by adding special handling whenever the ot...

Same problem here, me and a friend never had problems to join each other in moded games since 2 years. Yesterday it worked fine, but today since 0.17.7 it does not work anymore. We uninstalled the mods, reinstalled. Does not help. We are 100% sure we have the same mods with the same versions. If yo...

I don't believe it's a campaign issue either. This really should be moved to the main bug report forum as it affects the save game screen globally.

And no, you don't have to delete every 0.16 save, only 0.16 saves that were of the campaign missions. At least, that's what fixed it for me.

Still happening on 0.17.7 but I've verified that deleting my old campaign saves (the "A New Hope" ones) means that this message no longer pops up. The bug therefore is better summarised as: "Error appears on the save game screen whenever old 0.16 campaign save games are present" ...

Now that 0.17 is out I'm posting updates to Dectorio with both 0.17 and 0.16 releases as many players are electing to play both versions. I've noticed that this introduces some odd behaviour when using the mod portal. It seems like it assumes that the last uploaded zip file is the 'latest' version a...

Is it possible that there's a limit to the number of GUI elements that can be synced in a multiplayer game? I'm noticing that if I draw a GUI with a small number of child elements it's fine, but once it goes over about 1000 children, then desyncs occur. In single player, it doesn't seem to have a pr...

Thanks for taking a look. I agree with the observation about the functions... I'm slowly trying to clean it all up! If it's another mod causing it, is there an easy way to narrow down where that might be? The desync I was sent has 57 mods installed!

Before I start, I realise this is going down the rabbit hole a bit because desyncs can be quite tricky to narrow down. I'm trying to be a good mod citizen and learn how to avoid these from happening but still have lots of problems I can't seem to solve. I understand Factorio is deterministic and why...

I should also have said that it's still an issue on 0.17.5

It happens whenever I try to save a game. It can be a brand new map or an existing save, as soon as you go Menu > Save game, the error immediately pops up. I suspect it might be iterating over the saved games as I have some from the old campaign, and if I select those in the save list, the error pop...

I keep having this issue too.

I was able to reproduce this and it was an issue in Dectorio. I've released an update that mitigates the issue. Try again with Dectorio v0.9.2.
