[FIXED] [1307.18], [1328.3] Mission Editor Causing Reproducible Crashes

[rosolano079]

All,

I'm currently on the Steam stable branch, 1307.18. In this version, as well as beta versions 1328.2 and 1328.3, I have experienced that building missions in the Mission Editor causes significant lag and eventually a silent CTD. I have attempted to diagnose this; what I'm seeing is that beyond some quantity of missions, the Mission Editor window begins to lag and momentarily freeze on opening. Then, selecting missions from the list on the left further causes input lag and freezing. Changing tabs, between Mission Settings, WRA, and EMCON also causes lag in rendering the window contents. Once the window fully loads, there is no degradation of performance; that is to say, the lag and freezing is on changing tabs or changing missions, not the entire application itself. The application as a whole is responsive as normal outside of loading missions in the editor. This lag and freezing worsens, I believe, each time the Mission Editor window has to re-draw itself, until eventually the application silently crashes to the desktop.

I browsed the exception logs and saw nothing that I think is related to this or a crash. View this Google Drive link for exception logs, crash dump files, screenshots of process performance, and a handful of saves. I recommend starting with Save 06B, which will repeatedly and regularly cause a crash for me just by viewing or changing parameters in the Mission Editor. At each point where I added a mission, there is a separate save, including a clean save of the scenario before doing anything to it at all.

I hope this will help someone on the team diagnose the issue. I am open to the possibility that this may be unique to my particular hardware, OS install, or what-have-you, and if so I would welcome feedback on something I can change that might prevent these crashes.

I have the same problem with 1307.18

I’m still getting this as of 1328.6.

Dynamic missions seem to be the main culprit, as I experience frequent crashes while setting them up.

I also get brief lockups when renaming missions or changing doctrine.

Have seen this also working in the mission editor. When switching between tabs (units, EMCON, WRA, etc.) it will start to gat laggy and then it will CTD. When you restart, if you didn't save, all your work is gone and you have to redo.

I now save after every change I make in the mission editor to prevent me from having to start over.

It does seem to do this with many missions in the editor and several of them are TOT's and TOS's.

Is there anything I can send to help I will.

This didn't happen to me until I went to version 1307.18.

Hi rosolano079, thanks a lot for your commitment and for the super detailed post.
A possible solution is implemented into the codebase and it will be available with the next update release
thanks again
