(solved).-Forcing walk animations to do a full cicle before stopping.

Maybe a virus scanner, or a music service like spotify... or the search-index function?

Aye AV are a pain. I tend to disable them whenever I want to play anything, though they shouldn't really affect fps all that much on a VS made game. Large ass animations on the other hand...

Hahaha, I was testing some stuff and had several characters with the same sprites to save time, one of those had an older version of the walk cycle and it had an offset midway, so I had the wrong one set as the player character and was checking on another one instead and didn't spot the problem on the character, and I was doing clicks at right about the same spot the animation had the problem.

Well, we all make daft mistakes at some point!
