It is possible the fault may have been masked before. The village building error is an exit error and non-fatal. Although you can set and build buildings that require but a village level, the game complains with the non-fatal exit error report if you assign buildings to villages in the descr_strat.txt file.

You can use a script to have the game place the buildings in the villages at game start though. Evidently everyone can get this to work except me :) so you should be able to do it: https://forums.totalwar.org/vb/showthread.php?t=63561
