To @bestekampfpilot58 and others...
I tested Claymore's Fw190 mega pack (for 4.10) in 4.11.1m+SASModAct4RC.
Finally I tell you Claymore's Fw190 mega pack has java program codes problems in thier deep place to 4.11.1m compatiblity.
Missing some textures, some msh, some cockpits etc.etc. are caused by this imcompatibility to 4.11.1m.
Those textures, msh, cockpits 3D/2D exist right as a datafile, but unstable java codes go to those strange behavier and write out strange error log.
Error log messages are not reliable on 4.11.1m SASModAct4 with Fw190.
SAS Engine,AI MOD(03-Jan-2013RC) for 4.11.1m is not due to this unstable. Without Engine MOD , 4.11.1m can't treat Claymore's Fw190.
In the other test folder 4.10.1m+DBW1.71+SAS Engine,AI MOD(03-Jan-2013RC) , Claymore's Fw190 mega pack (for 4.10) runs perfectlly and no datafiles missing.
I checked.
I decide myself to wait a new 4.11.1m version codes of Claymore's Fw190 pack that's fully compatible 4.11.1m.
To @Claymore...
If you have enough staff to make java codes converting to 4.11.1m compatible, then I wait you.
If you want to help , I can help you around java .
