What in the two universes could cause this error, in a quest file:

Invalid tile format encountered.

The file is saved in ZQuest 2.50.1 (Build 28), and opened in ZC 2.50.1 (Build 28).

Saffith/Gleeok: If you need the .qst file, I can send it to you privately. I think this must be a format bug with the packaging encryption, or compression... ?

I've never seen it in the past.
