So we had a Foundry and a Glass Forming Station placed next to each other. At first the foundry was functioning fine when there was no Glass Forming Starting, but then, during crafting, the UI for the foundry was replaced with the Glass Forming Station and all UI's and tooltips and actionbars got locked out. We couldn't access anything, nor change what we were holding at all and had to close the server. Once we opened the server, the foundry was gone, with everything that was in it.
At the time of each crash, there was nothing being made in the Glass Blowing station (although it was lit), but at the first crash the Foundry had a Steel Ingot and a Iron Table (container) going. The second time it glitched out was when I asked the new foundry to produce another Iron Table (container) and as I clicked ''craft'' the required items were taken from my inventory, but the table didn't appear in the crafting area. I closed the foundry UI, and reopened, only to find it now having been replaced by the Glass Forming Station's UI and the same UI/tool lock out happened, forcing us to do another server restart (after which the foundry was yet again missing). Sadly, we didn't get a screenshot of this, but I hope I could provide enough information.
Edit: After the second crash we put the foundry at a solitary location and retried crafting the Iron Table (container), only to have the Foundry UI glitch out again. It takes a little while, but the entire server locks out from actions again. For unrelated reasons the other person was unable to restart the server (internet died), so we couldn't check if the foundry was once more gone.
