Roblox studio corrupting my scripts?

hello i am a TC dev (yeaaah its me)
and today as i woke up and join the tc, i see my elevator script has got corrupted, a line of tween HAS got deleted. it caused the whole script to bug and error… i restored the tween BUT i dont know what causes the corruption, there are 2 TC Devs, one (first tc dev does not have any plugin because hes on a alt.) of them probably have clean plugins and so do i. im pretty sure im blind and i dont see any malicious plugins, i probably have clean plugins but expect to for content deleted that i already deleted. any response?
