Replicable FA Hang on Factory Assist

[nine2]

Hello,

I am finally able to reproduce a bug that has hung FA for me many many times.

Make 5 land factories. Each one assists the previous one.
Set first fac to infinitely build units.
Set last fac to infinitely build units.
Select middle 3 facts and tell them all to assist last fac.
Within 14 seconds game will hang, process has to be killed.

Example Replay Id: 2552022
No logs because they don't save.
I have replicated this problem 4x tonight and have had someone else do it as well by using the steps above.

This bug doesn't seem to happen with 4 land factories! Has to be 5 or more.
I assume to workaround just stop factories (which clears assistance) before assisting new building. Maybe you also need to clear the assistance of the factory you are assisting as well.

All mods disabled (even advanced strategic icons), playing in windowed mode.

Thankyou!

So the first factory is not assisted?

Did you shift+assist?

When I build a support fac, I usually order one engi, then shift+assist to HQ.

The first fac is assisted originally by the second fac. When you change the 3 facs then the first one is no longer assisted.

I didn't know about shift-assist but now I do and the answer is no.

Easier steps to replicate


Setup factories 1, 2 and 3 so they are all assisting each other in a circle.
Setup factory 4 and assist any of 1 2 or 3.
Build a single unit with 4 and it hangs.

Yea, I managed to replicate this. Very strange....

Here are logs:

I accidentally just did this bug again in a ranked game, replayId = 2565385

I got some log files this time so I have attached them.

This bug has now been confirmed by LoveSocket, The_Koppa, Zock and me

If this bug can not be fixed I think you should delete this forum post since it's very abusable - I could crash every game of Ranked that I was losing if I wanted.

I understand that I don't get a reply if there aren't logs posted but I swear on my soul there was no game.log the first time - I checked it and it was for the previous game.

I was probably reading replay.log instead of game.log

I've checked, that bug exists since Supcom vanilla.

I don't know if it's a script error or an engine bug. Hopefully a script error, or something we can detect and avoid with a script, but it needs further investigation.
