Yeesh, that damage loop is a nasty one. Ran a quick test and I'm not seeing though; struggle seems to work as intended. Was it a one-off, or can you reproduce it?
Good catch on the second one. Forgot to change something when adjusting skills for this update. Hopefully by "struggle" you actually meant the "resist" command, that's what I was seeing persisting too long. "Struggle" seems to be behaving correctly. Got that fixed for the patch.
As for github/collaborative stuff, I appreciate it, but I don't see myself doing anything like that in the near future, for the same reason I avoid Discord and the like: it's one more thing I have to manage and tend to. And thankfully, the nature of most RPGMaker bugs is just "oops, forgot to change that code to point to THAT switch instead of the other one," or "Oh right, I have to do that and then THAT in the code." Simple omissions or substitutions, rather than the nasty code digging and reworking you'd have to do in a more serious programming project.
