Hmm OK, probably due to the changes to the sessioncomponent section with the update. I will pull it apart and try and resolve it over the next few days; a bit hectic with work at the moment sorry.

thanks

im also getting a crash when trying to copy a ship with this mod on it, so i dont know if you can fix but good luck, also amazing work

Thanks again for the bug report fellas. Please give it another go, hotfix just pushed through.

When I activate the block, the crash game.

Full re-code happened today, fingers crossed all crashing action is a thing of the past. For reference, copies/blueprints were activating the block before it had a physics object assigned, which was obviously not ideal as the cloaking references the physics & render objects. Simple check added to the new code.

Game is crashing to desktop when exiting multiplayer with this mod. It seems to have something to do with thrust:
