man you have one missed up cage in there, still trying to figure where is this crisscross thing

dunno what to call it i had this virts/edges problem something is connected in a wrong way that chamfering one of those edge points should give out 4 points cause 4 other points are connected to it instead its chamfering 5 points and the fifth is like floating

so i did a series of useless cuts, and i was write some edges couldn't be connected cause the polygons are either flipped or something so i forced it to work by making a whole cut in this shape on all faces + then re welded some of them and fixed that edge.
ONCE I COME UP WITH THE PERFECT SOLUTION I WILL UPDATE YOU
sorry not too quick on replying and even ditching my projects have to finish five 20sec animations in one day for work.
