Dynamic vertex slopes only work correctly if all vertices have a linedef tagged to them
This makes it difficult to set up dynamic vertex slopes where only one or two vertices are supposed to move. Interestingly enough, this is broken in both 2.2.10 and in next
, but in different ways.
In 2.2.10, these dynamic vertex slopes are close to working properly, except that all untagged vertices get their height set to (absolute) 0:
In next
, any dynamic vertex slope that doesn't have all three vertices tagged does not move at all:
