heads disappearing

[callimuc]

lately, i have realized that player heads seem to disappear in certain ganis. when i'm having the gani set on myself, everything is alright.
this happened to me on a UC server i have been working on (it's using its own ganis where everything is ok) and on Graal The Adventure so far. the head files were OK, ganis werent broken and so on. i have been told that some other players seemd to have similar problems, im not sure what version they have been using. i'm using the latest v6 version (6.037)
