The issue with the rewind bar is that i cant save every point of every prop all the time (i made some tricks to not sace all points, like ignoring points if the props aint moving). so at first i limited it to the duration of the rewind bar. but i had a problem that the save point duration was kinda low, so i made it that you could save TWICE the duration of the rewind bar, without increasing the rewind time (Because i didnt want to make you able to rewind non stop). im gonna check out the rewind bar duration
thx for the feedback :D
