There will be poker games held on the industrial engineers server when in launches in a month or two

hmm... I'll stick to the slots

You can play against yourself. The area in front of each seat has interaction where you can buyin chips and place bets. The middle of the table interaction is for starting rounds and collecting winnings

I assume the poker table cannot be played in singleplayer?

I will try to fix it :D

display boxes / unable to place items in them. unable to place gems on or in things. broken hitboxes.

The display boxes?

trading post still aint been fixed XD
