Congratulations, you made the mod potentially have a memory leak that's impossible to revert on top of other issues, which will lead to people losing 100 hour saves instead of 5 minutes of progress

who cares? my task is to make sure that I don’t waste my progress because of some mod

If you count losing 100 hours as no lost progress then i guess i don't have anything else to say, have a nice day and pray that you don't have that happen cause it's the only thing you can do at this point

and errors in 99% of cases occur when the entity has already been deleted, even the author of the original mod corrects this using the valid_for_read check method or something like that. also the average game time is ~50-100 hours so who cares?
