For whatever reason, I seem to get the error a lot, ever since when I first started using the mod in 1.12. The issue I face, is that I record a replay file, and it seems fine, however as soon as I go to open the replay file to add keyframes and such, it comes up with an error in chat telling me "Error loading entity tracker: decoding" This previously would mean that it wouldn't let me place keyframes, however now it simply crashes my game. It get's very frustrating, because I don't know what causes it. I believe this is a bug, but if not, and I'm doing something wrong, please let me know. Thanks!
