...then it's a bug in MUGEN. Our intent is for 1.0 to be backwards compatible with content made for 2002.04.14 without any changes needed on your part. This release candidate has some very visible bugs that affect a lot of content.
If you experience something that doesn't work, please check if it's a known or reported issue in the bugs forum, then post it if not.
Don't delete your old copy of MUGEN yet till we've ironed out the bugs in the 1.0 RCs... thanks for your patience.
