Submitted v2.9.0 update with major fix for “auto destroy” mechanism and the “Procedural” interface events that were not firing properly due to previous changes to the SGuid usage (check past posts above).
I take save file incompatibility very seriously and I try my best to never break old save data, but this time I cannot achieve that unfortunately…
WARNING!!
So, if you have live project and don’t want to risk compatibility issues in old save files, I recommend you make a backup before you try v2.9.0.
I do not plan to push any serious updates anymore this year, exactly to keep save files compatibility as solid as possible across engine versions.
