[Help]Quick question regarding a bug (Rune files)

[kremitt]

Hi,
first of: I'm new around here, hello RZ-community!

Now, regarding my question:
A few friends of mine and me started developing on a fork based on Rune-src a few weeks ago (expect the results to be posted here some time in the future), and have been doing well until now. Recently, we started trying to fix a specific bug:
When a player wears unequally upgraded armor or weapons (e.g. upgraded to +1, +3, +5, +7 or +9), other players cannot see those equipments, unless the player re-equips them right in front of their eyes. Upon walking out of the screen and coming back, the bug appears again. This, however, does NOT apply for elemental upgrades. Also, the equips seem to be indeed INVISIBLE, as Knight's hairstyles still get deleted upon equipping unequally upped helmets (enabling other players to take a clean look right into the Knight's head ;D).

Now, I'm not asking for a fix (unless this is a known problem and there is one already =P), but for directions: where do we have to look for the problem? Up until now, we were unable to find the bug in the src. Is it a client-side problem? Or is it really the source? Oh, and the search-button didn't help, either.

Thanks for answers in advance!
