Apologies for the downtime today, we had a glitching block in the main world and it took us a little while to track it down and remove it!
The glitch was made worse by extreme lag from a high number of lag producing items (way above the limits) which meant we couldn't get close enough to remove the glitching block manually (despite trying for over half an hour), as a result we unfortunately had to regenerate the area which destroyed half of the players factory. Please do remember to stick to the item limits we have set, we have them for a reason, thanks!
You can find details of the limits here.
