Hi, I tried to post this on GitHub but my account was flagged (maybe because it's new?) so no can see my posts there, I'll just repost what I said:
Hello. First let me say that I really, really love this mod and have been able to use it with no other issues, for the most part. However, whenever I separate a stage with multiple struts or a ship is destroyed and produces a lot of debris, KSP (v. 1.10.1) crashes and produces a fatal error; an example would the 7th stage of the stock Acapello rocket.I thought this might be an issue with RAM usage, but according to Task Manager RAM usage does not increase above normal levels during the crash. I am able replicate this crash every time I try. Not sure whether this is a bug or a performance issue with my machine (Intel Core i7-9750, RTX 2060 6GB GPU, 8GB RAM).I can repeat this crash on a fresh install of KSP with no mods other than Principia. I have provided the info.log and fatal.log files.
Many Thanks.
