Summary
None
Purpose of change
Fix #72960, e.g. the map::collapse_check logic being incorrect.
Describe the solution
Remove the static assignments in the loops with a single check at the top and bail out when a tree top is processed.
Describe alternatives you've considered
Leave it to someone else.
Testing
Chopped down a tree that had a tree top and verified the treetop was gone afterwards.
Then hacked the collapse check to return a really large number, virtually ensuring it would never roll a collapse and performed the tree chopping again. This time the treetop remained.
