So, I managed to get two Science hubs in and working in one of my science labs. I think this happened because I added extra tiles to the bottom of the lab in an attempt to put two in there, I moved the existing hub down so it was half in the existing room and half in the blueprint portion, then I was able to add the second one in without many issues. As you can see below, students were using both of them, however after attempting to add something else to the room the game started flagging up that I could only have one hub in the room and forced me to delete it.

Since I was streaming, here's a timestamp to where it happened in case there's some info in there that helps reproduce the error: https://www.twitch.tv/videos/1563871059?t=1h44m59s

Hey iviv!

Thank you for the clear steps and for the clip! I've alerted the dev team to this issue to get this resolved.

I hope you're enjoying the game!
Thank you!
