Quoting the A21.2 b30 patch notes
"Fixed
POI trigger system not working correctly when utilizing multiple triggers to trigger another item"
So, you might be asking, how is it broken even further than it was before?
Before b30, if a block is 'triggered by' multiple triggers, you needed to trigger ALL of those triggers to activate that block (for the most part, it was buggy and not fully working correctly)
After b30, triggering ANY trigger will activate the triggered block, regardless if the other triggers weren't even triggered.
Example:

B26 and prior:
Press ALL buttons to open the door
B30:
Press ANY button to open the door
This "Fix" has destroyed the ability to make puzzles in POI's. Now it's a 'press any button for automatic solution'.
