Aquarium Snowflakes Glitch If you try to play an affected tank, all you will see is a completely frozen image of the water in the tank. The frozen glitch is due to the item
Aquarium Snowflakes being in the main inventory of the frozen tank's owner. If you suspect a tank is frozen, alert the owner in their bump thread (or by PM/profile comment if they don't have a bump thread) and ask them if they have Aquarium Snowflakes in their inventory.
Fortunately, the glitch is easy enough to fix. If you were informed that users can't play your tank since it is frozen, locate the item Aquarium Snowflakes in your inventory and move it to either the Locker or the House storage areas of your inventory. Save the changes and users should be able to play your next glow. You can also discard the snowflakes or send them to a mule/friend who doesn't use their tank. Moving the snowflakes to Locker, House storage, or Trash immediately makes the tank playable!
Dumpster Dive has been known to periodically grant Aquarium Snowflakes. If you Dumpster Dive and didn't see what item you got, check the aquarium section of your inventory. Better to remove the snowflakes right away rather than find out several frozen glows later that no-one can play your tank.
Sometimes it will take a moment for the booty grab game to start! Wait for 30 seconds and try a different link for the same tank before assuming a game is glitched.
