Just a reminder to keep off topic conversation to private messages. Don't go derailing the thread just because someone speaks a language you do, thanks!
Also Swex, glitching like that tends to occur when you get a body part inside Uke's legs. The interaction with cylinders (Uke's thighs and shins) plays out differently between making the replay and watching it. If you stay clear of ghosting into the legs and watch the replay regularly, you shouldn't have any problems with manipulations.
