Had a fun person through yesterday. Claimed the spawn trade portal was glitching for them and that it was a level 21 (and gave them a whole bunch of coins etc). Took a look and couldn’t click on the trade portal. Do a stop and come back and sure enough, the TP is a level 21.
Remove the portal and replace it with a level 6 TP. Player goes to portal, I see the upgrade animation, look at it and it’s level 21 again. Ban player but leave portal, since it’s a wrong level, but you can still only purchase normal things for normal prices.
Come back on today, take a look at the portal, now it’s owned by a different (non-admin) player, and has no base. Remove it and replace it, but it has no base but works normally (still shows as a level 21). Remove it, replace with a level 1 TP and upgrade it to level 6 and hope the player doesn’t show up again.
Now I have two Level 21 portals, they can only be placed on backwall otherwise they just collapse. Plus, they don’t show any base block, just the upper portal section. If you try and place a block where it’s supposed to be, it just despawns and goes back into inventory.
