World Editor: Save/autosave breaks

Dear BeamNG team,

Since a few updates ago I am getting a very strange error after a while when editing my custom BeamNG map:

Spoiler: Error

--------------- << END <<

As soon as this error appears with the first autosave, the asset browser disappears and the log becomes filled to the brink with this same error over and over and over again.

I have previously made a forum post about it, which also CONTAINS A CODE SOLUTION: https://www.beamng.com/threads/world-editor-level-cant-be-saved-after-a-few-minutes.100508/
HOWEVER, with every update my solution becomes reverted and the issue is present again. I would prefer if someone from the dev team could take a look at this issue, why it is happening and potentially implement my fix into the official game code.

I am available for troubleshooting through the official Discord server.
