When I have UAF enabled, the only way I can load a saved game is by starting Starsector from scratch and loading the game fresh. Under any other circumstances - for example, if I load a game, play for a bit, exit back to title screen, load a game, and try playing - I get the memory leak error popup. 100% reproducible, every single time. Having to quit to desktop every time I want to load a saved game isn't great.
Also very consistently, after playing for a while, saving a game starts getting slow and erratic, to the point that the game executable will freeze during the saving-game process. Random save corruption isn't great either.
This is stuff I have seen within the first year of game time, so it's not like there's a lot of accumulated data to save.
This is with version .72e1. I am using the JRE 8 and have modified my vmparams to use more system RAM (3072 is what I currently have it set to).
I also am using a fair number of other mods but the game runs very smoothly with them but not UAF - with the other mods and not with UAF, I've played for 10-20 years game time with no problems. I could start doing systematic cross-checking - UAF alone, UAF plus Nex, UAF plus Nex and one other, etc - but, I admit it, the thought of doing all that work is a bit discouraging right now.
