Using a custom loading screen places the race crest (orc/human/undead/night elf shields). Normally the banner shouldn’t be there, allowing us to place our own crests within a custom loading screen.

The problem is, we cannot replace webui\loadingscreen\campaign\crests\wc3_map_raceicon_orc.png with a different/empty png file. The game just selects the standard race crest.
If the workaround would work, this change would allow us to be more flexible in designing our loading screens/crests- but all old custom campaigns that had their own crest (and are unlikely to be updated) will suffer.
