So I've searched & searched but I can't seem to find a reason for/fix to my issue.

My issue is this: when I refit any clan mech or mech added by a mod, it becomes fixed forward in mechbay, loses the paper doll in pre-mission load area & in mission has no hud or map. How tf do I fix this!?

For those that may ask my mods are:
The Yet Another collection (no individual mech mods)
VonBiomes
Pilot Overhaul
Rebalanced Weapons (all in one version)
Omni Slots
Both Pax Optimization mods
Better warzone spawn/rewards (can't remember name exactly)
Advanced Career start
(A couple more but I can remember, will edit with an update if needed)

Any help is greatly appreciated, I really want to use my clan mechs as I fought hard for that salvage.
