I recently made the transition to the latest stable version of the core (098 of course :p ) without having encountered any major problems. After a few days of testing, however, I noticed a strange behavior of objects with graphics changed.
At each restart all the wearable items in the backpack with the graphics changed, become non-wearable. The only way to make it work again is to manually set the graphics through a command (with .itemedit command)... and obiouvsly this work 'til next restart of the emulator.

I've recompiled back the same codebase with 097 and this time all works flawlessly.

Any suggestion?

It's not a problem from the core... should be one of your scripts changing the graphics... But I still don't exactly understand the problem.
