BYOND Version:513.1508
Operating System:Linux
Web Browser:Chrome 79.0.3945.79
Applies to:Dream Seeker
Status: Resolved

This issue has been resolved.
Numbered Steps to Reproduce Problem:
1. Update to 513.1508
2. Run game for a while
3. Experience crash. (Sorry, I can't find something that reliably causes it beyond "play for a minute or two".)

Expected Results:
Dream Seeker does not crash.

Actual Results:
Dream Seeker crashes within a minute or two.

Does the problem occur:
Every time? Or how often? - I was unable to run DS for more than a few minutes at a time.
In other games? - Unchecked (I was only testing Goonstation)
In other user accounts? - Unknown
On other computers? - No crashes in native Windows 10

Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? (Visit to download old versions for testing.)
The problem did not occur in 513.1507. It has only begun happening since upgrading to 513.1508, and it stopped happening upon downgrade to 513.1507.

Downgrading to 513.1507 (or earlier).

From looking at the code I think I might have an explanation for this, but if there's any way you can narrow down the types of animations that cause this, it would help a lot.
I have a potential fix for this in 513.1509 but obviously I can't test it because I can't reproduce the issue. I'll need you to recheck in the new build once it's up.
