In the editor, when saving a custom campaign, all text in custom data from the campaign are reset to their standard values. This affects simple text values as well as paths to models, icons etc.
Does not affect hotkeys or icon positions. Functionality (triggers) also not affected.
Simple example:
- in the campaign editor, copy a footman to create a custom unit.
- rename that footman to anything else.
- save the campaign; restart editor; load that campaign = footman will be named footman again.
