I'm seeing the same exact issue on f450264
Windows Clients, Linux Server.

It's like the client never tells the server that it obtained those resources, so they're lost when they rejoin.

Had the exact same issue, i think it also has something todo with the not working animation/action sync of the exosuit.
Hope, this gets fixed, relatively fast, with this fixed, it would be nearly playable.

my thoughts on that, even if i dont work on nitrox:
The Actions Sync of the Pawnsuit Arms doesent work, the only arm thats working is just the Grappling Arm and even there, the action of the arm is not in sync, only the movement the player/exosuit gets though the arm.

And the big ressource vein will "respawn" if the player who mined that goes away and comes back, to my knowledge it isnt like this in the singleplayer. That tells me, the playerinstance(of the player in the suit) wont tell the NitroxServer that he mined the ore/used the Arm of the exosuit. I looked into the code of nitrox a bit and found something to sync the Action of the arms but i guess this wont work anymore or is just buggy?

Idk, i hope that my thoughts on that could help a littlebit with debugging that shit, good luck guys and hopefully not to much of a headache. ;D
