repost... but please help

[GoldenRivet]

well i searched the forum and the manual to no luck... mostly because i was unsure of the key words to search for.

But here is the situation:

GWX2.1 has been running great from date of release.

finished a 12 patrol career with no trouble through SH3 commander.

Started a new career to continue with a new kaleun where the old one left off.

now the u-boat interior is missing... **sometimes** but not all the time. one minute it is there, the next minute the entire command room and radio sonar room/ captains bunk is missing textures and crewmen with only a visible radar screen in the lower left hand side.

i KNOW this is a repost and i have been looking for the solution.

i think the problem has something to do with the fact that my last boat did not have radar, but now, this boat comes with radar and i think radar is causing a problem somehow.

i have not installed any new mods

currently using:
GWX2.1
Sh3 Commander
GWX no medals on crew
GWX open hatch
GWX das boot movie
OLCE2
OLCE2 special
Lifeboats and debris

did not notice this problem until the boat was equipped with radar. question is whats the fix?
