Fixed.

Thanks for the reports and videos and all. Thanks to it I was able to recreate it and eventually fix. It is basically the same issue I had back in the day when I was doing similar things for belts (to avoid gaps when run-building them when moving fast).

HI, thanks for reporting it, I am looking into it.
Can you tell how to reliably reproduce it? I have not yet found the conditions under which these things happen.

Hi, sorry about that. Fix will come soon. Thanks for the help.

I also already did. Fix will come soon.

Thanks for reporting. This is from a fix I was doing yesterday.
Can you send me a screenshot or something of how you reproduce it? I was not able to do it so far. Also how fast are you? The fix was for building power poles on high speed.

No, as I wrote - it will mine the ore which it has the fluid for.

Yeah well, in theory the miner can be used for different resources that require fluid and will mine whichever one it has fluid for. So can't be done.

Hi, thanks for the crash log. But what would help mainly is an information about how it happened.

Yeah I think so. There were some reasons against it though but I will have a look.

I can see similar crashes in our automatic crash reports, so I can only assume that it still exists. I will research it deeper now. Please, let me know if you discover anything helpful.

Hey, I am sorry, I have overlooked this one. I fixed these things in some 17.17 or so. So I will put this to resolved, reply in case you still encounter such issue. Thanks!

Hi, I tried what you describe and it seems ok. I suppose it is not happening anymore, right? Many bugs around BPs have been fixed since.

Sorry you had to go through that.
Could you just try to load the save in the current version? And if it still fails, then it would help if you upload it and we could have a look at it.

Hi, do you still have this issue? Unfortunately the save is not there anymore so I can't check. Thanks.

Hi, is anything of this sort still happening? Many fixes were done since that version and it should probably be ok.

Hi, thanks for reporting. This uses an entirely different mechanism which did not have the reporting yet.

Hi, this has been fixed in the mean time, the structure is now indestructible. Thanks for reporting.

Hi, I am assuming this is no longer valid? A lot of changes and fixes of trains happened since 17.4.

You are right, thanks for reporting. Fixed for next release. As a hotfix in the meantime you can use a single click to interact with sliders.
