Bug: Hammer crashes on undo

[spiro9-peef]

Describe the bug

Hammer crashes whenever undoing any action.

To Reproduce

1. Open any map file
2. Make any change
3. Undo that change
4. Hammer should crash

Issue Map

Not map specific.

Expected Behavior

Hammer should undo the action instead of throwing a conniption fit.

Operating System

No response

Undo system is not broken as much that it is not unusable. Please provide actual vmf (and steps to reproduce) that does cause it to crash.

[spiro9-peef]

It seems to be more inconsistent than I thought, but seems to be primarily linked to large changes in textures or at-random with certain operations to entities. I'm not sure if sentry is active or not so I don't know if Strata devs are getting the crash reports.

This may be fixed in the next update, if it was what i think it is

@peefTube is this still an issue?

[ozxybox]

Closing, as this should be fixed if it is the issue i think it is. Also no response since july
