On version 5.12, after initialization:
- Open rom in LM, open Map16, change tile 2A0 ActAs to 290
- Save Map16.
- The tooltip for 2A0 shows the tooltip for 290 instead. In-game, 2A0 behaves like 290. GPS gets tile 290 from LM in-game -- the custom 2A0 block code is not run.
A callisto full rebuild fixes it. Changing the ActAs to a vanilla tile instead seems to work fine.
