setResourceInfo often not working

[Mdbelen]

Hi there, i have a little big problem with the setResourceInfo function.

I want to use it to save a tostringed number as attribute "cid" to all race maps on the server. (e.g. )

Sometimes this works, but sometimes it doesn't; i really have no clue why.

Often when i want to set or change the value it just doesn't change the file(meta.xml), though it returns true

If I use getResourceInfo for this attribute then, it returns the new value. But it just doesn't save it to the file, not on refresh(all), not on servershutdown.

After serverrestart getResourceInfo returns the value stored in the file (=the old value) then.

Possible that i do something wrong, or is this maybe some "cache-bug" in mta?? (all resources are not zipped)
