Sorry to hear you are having trouble.
If you have a savegame where this is reproducible it would help a lot if you uploaded it to a cloud service (DropBox, Google Drive, One Drive) and post a link here, the developers can take a look at it.
Savegames are located in \Documents\My Games\GC3\Saves or \Documents\My Games\GC3Crusade\Saves
Thank you for your patience and patronage
