Resolve this either by removing the terrain from this mapgen, adding suitable removal commands to the mapgen, or by adding a suitable flag to the innermost mapgen: either ERASE_ALL_BEFORE_PLACING_TERRAIN if you wish terrain to replace everything previously on the tile or ALLOW_TERRAIN_UNDER_OTHER_DATA if you wish the other items to be preserved

Here is the save file. I hope it is able to help somehow.

Looks like #54765, just for a different map extra.

[matshou]

Should we close this issue as a duplicate?

[mqrause]

No, the different map extra makes it its own issue.

[NetSysFire]

I wonder if it might be caused by #54344

[mqrause]

Yeah, that added the debug message.
