Factorio Forums

Here's my log file (with my name redacted and replaced with ~): https://pastebin.com/AnXiNpqx

I am playing the seablock mod pack and clicking on the "Armored Railway" technology in the research screen causes the game to freeze. It doesn't crash it just stops responding to any of my inputs and windows doesn't recognize it as not responding. As far as I can tell the freeze happens only for that technology and none of the others. The freeze does not happen if only using Angel's and Bob's mods, adding the seablock and seablock config makes it happen. I also tried updating the mods and the freeze still happens.

How to replicate: Open factorio and load a game/make a new game. Click on Armored Railway tech.

Thanks for the report however I can't reproduce any freeze. I downloaded the latest seablock zip file, loaded the game, and when I go to the tech GUI and select the armored railway one it works just fine. I tested a new game and unlocking all technologies and it works fine for me.

Can you upload your mod settings.dat file? Did you make any changes to settings that could effect it maybe?

Deleting the settings file fixed the problem so I guess that was the issue. I don't recall editing it, not even sure how I'd do that. The forum wouldn't let me upload a .dat file so here's a dropbox link with it: https://www.dropbox.com/s/hfgh781dj2qyd ... s.dat?dl=0

this issue reminds me of similar issue, where someone reported, that his game froze, when selecting certain technologies, while having SCTM installed (mind SCTM is also part of seablock modpack), for that person fix was to disable connecting science packs with technologies.

to explain, science pack connection does iterate trough research tree, and connects technologies with relevant science pack, if there is no previous technology with same science pack set.

so let's say, you have technology that uses chemical, automation, logistic, and as prerequisite it has only technology that uses automation (or even only logistic), in that case it will add chemical science as prerequisite ...
while this itself is not gamebreaking, it does in fact create more complex science tree, and if you click on science pack, you might see much more stuff connected to it, than normal. having such complex tree might be taxing on low/mid spec computers (while i had not yet experienced such issue, i can imagine with some mod combination, it can happen).

i have attached pictures, to visually explain what i mean with connect, and what impact it can have on tree - and this is just vanilla and SCTM if people have multiple mods, of course this connections are more complex. so perhaps some "optimization" of research tree might be required, to avoid hangup/freeze described by OP.

then again i have not experienced this freeze, yet it has been reported to me since i added science pack connection (back in 0.16)

as for op mentioned, clicking science pack usually doesn't create problem but clicking direct descendant technologies does.

Thanks, fixed in 0.17.43.
