Updating surfaces.pck issue

[comper]

Hello,

Its about Jade Dynasty, but i assume with PW can be similar.

After i update midmaps files (example: surfaces/midmaps/z1.dds) and put it in patcher (i tested sPATCH and CPW) it updates well.

But ingame i can still see old map.

I unpacked surfaces.pck after this update, and the NEW file is inside.
(Only packing whole surfaces.pck from surfaces.pck.files using spck.exe works - but CPW won't handle full .pck file )

Do client keep files like that in some kind of cache?

Any ideas how to solve this issue?
