I wouldn't bother with editing the mis files, and I do not recall which files are actually used for the Monsun Gruppe boats. There are all sorts of "Indian Ocean" PatrolObjectives files, but most of the ones from Stock are not used, so it's almost a waste of your time to try and edit the files.
I would be very tempted, if it was my computer and SH4 install, to de-activate all of the OMEGU and OM mods. Then un-install Silent Hunter 4 from the computer. Then delete the "C:\Users \UserName \Documents \SH4" folder, or where ever you happen to have your Save folder. After that, re-install SH4, making certain to NOT put it in a Program Files folder. Edit the install path yourself, and install in a folder you made. Then bring back in JSGME, LAA (read CapnScurvy's
Windows10; Large Address Aware; SH4 Install thread) & MultiSH4 (if you use it). Run JSGME and use the "Create snapshot" ~before~ you add any mods.
After that, add your mods, being certain that the folders are all correct. Look-out for folders double-named, such as "MODS \ OMv705_to_V720 \ OMv705_to_V720", and remember that some of lurker_hlb3's mods are inside a "collection" folder, such as the "OMEGU_v300_pkg", which holds eight (8) mods inside of it...
I would do the "base" OM, updates and patches only initially, and see what it looks like. Delete the Save folder again, and add-in OMEGU, updates and patches and run it again. Then you could add in other mods and see what things look like. Be sure to delete the Save folder between changes!
