Hey Nealius,
just wanted to let you know I'm struggling with the same or at least a similar issue.
It started with creating a mission from scratch for singleplayer training where I'd put a supercarrier group with a lot of statics (planes and people) first and then extended with mission objectives and so on. The mission was playable for some time (don't remember how long or when exactly or until which beta update) and then it stopped working to load in singleplayer. A friend of mine was able to load it in singleplayer and joining this same mission in multiplayer was no problem. Only starting this mission at my end in singleplayer didn't work anymore and resulted in the same "us carrier tech table" error in the log and it freezes at "sim post start" in the loading screen.
Joining a multiplayer server or any other mission (trainings) with the supercarrier module works fine so I tried to find the error in the mission but with no luck until now. I tried short and long repair, deleting mods (high digit sams and sam site asset pack which I didn't implement so far), deleting the save folder and tried to check if any parameters are outdated (I found only one specific loadout for the F-14 not working anymore but this didn't solve the issue) or if anything collides with the supercarrier. I even checked the scripts (moose, mist and skynet iads) but they aren't the problem as you can see below.
After several hours it started a single time after moving a static F-14B for a few feet but the next time this didn't have any influence anymore and it won't start again. I only got the mission running in singleplayer after deleting the whole supercarrier group (removing only statics won't help) so I assume it's the supercarrier in any way.
I'll follow this thread in hope to get any further ideas.
