I was going into ewithin.hog to simply resave a level so it has the correct creation center information, and when simply loading the rl2 and clicking File-->Save after it is loaded, it causes:
1) D2X-XL crashes loading the level.
2) DLE-XP crashes loading the rl2.
So there's probably something corrupt with how it is saved. A log from D2X-XL loading the level is attached (same log as is attached in my D2X-XL ticket).
