hello! please, can someone help and tell me what am i doing wrong? i remember always using glue for lip and lip skin while rigging the mouth. i took an approximately one year break and now im trying to rig a model for my boyfriend, so maybe im just forgetting one extra step or a mistake i made that i cant seem to find myself? i have to relearn a lot of things as well so im almost 100% sure the issue is me and not the software. videos dont help much with this and i cant find a post about this specific problem 😞 also, i couldnt capture it because it stopped after hitting the capture button of course, but im sure it will come back so while im here i want to ask about another problem too: the add point tool in manual mesh edit mode randomly starts putting down two points instead of one, the "main" point (green) and a red one below it. what that would be and how can i disable it? thanks for the help in advance and sorry if my text is a bit goofy, english is not my first language AND im on the verge of tears D':
