[posila] [1.1.3] Crash during blueprint rotating when blueprint contains Splitter

[VyacheslavEnis]

Hi,

I have a problem which can be almost 100% reproduced using my save with provided set of mods. Steps to reproduce this crash are following:

• Load savefile
• Create any blueprint which contains splitter (just 2-3 splitters are enough)
• Select this blueprint
• Rotate it couple of times (sometimes 2-3, sometimes 10) without placing.

At some point game just freezes and log file contains information about actual crash. I've seen two different types of the crash in the log:

First crash has following in the log:

Code: Select all

Second one - following:

Steps to reproduce and visible results are completely the same. I've attached both logs and actual savefile.

Just got completely the same crash with same log file content just by moving blueprint with splitters and belts only without any rotate. Log file attached

[VyacheslavEnis]

Also maybe it will help - the game is freezed and need's to be killed manually after crash. So it's not closed and still running as "Not responding"

I can't reproduce the issue crash even in 1.1.3. Could you please post also blueprint I should try to rotate and specify where on the map should I be hovering it when rotating it? (does it crash even if you do that in a location where the blueprint doesn't collide with anything, nor connects to any belts)?

[VyacheslavEnis]

Actually it doesn't depends on any specific blueprint. I've reproduced it couple of times just using following steps:

• Load attached savefile
• Place 2 or 3 Splitters
• Copy them and put to the inventory as a blueprint
• Grab this blueprint and move mouse around a base (even without rotation). At some point )and I don't know when, it's always random place for me) game will just freeze and needs to be force closed. Game log will looks like as one of the attached logs

Does it happen also in 1.1.5?
I still was not able to reproduce it.
This is blueprint with 3 splitters I am using:

Will try to reproduce it in 1.5 and will post a result.

Will try to reproduce it in 1.5 and will post a result.

Thank you very much!

Checked on 1.1.5 with all used mods updated to the latest version. Got the same freeze with yours splitters combination. Crash log contains the same:

Please also include the save file(s), any mods you may be using, and any steps you know of to reproduce the crash.

Also I've made screenshot right after game freezes. Single blueprint in the quick-bar is the splitters in the hand. Just moved around. Also I've noticed that almost all if not all crashes where when mouse cursor was near the place in the screenshot. I've tried to move mouse to the left near the copper belts and it's not crashed at all. But when I moved my mouse to the right side - it's crashed again. Maybe it's somehow terrain-related? :

Thanks for the report.
Fixed for 1.1.6

Your screenshot made me realize something I didn't pay attention to before, and that's that there are camera widgets. It was race condition between rendering of camera widget and game view, due to building preview temporarily modifying map for buildability checks and connecting belts in the preview with real belts (etc.)
So that meant, the larger blueprint the higher chance the crash will happen, and that helped me to reproduce the issue and fix it. Thanks for the additional info.

[VyacheslavEnis]

Perfect. Thank you.
