I'm having mouse issues with this release. Particularly when placing or moving blocks. Sometimes when I try to place a new block it will place two or three, and dropping them while trying to move them even though I haven't released the button yet. I'm not sure if it's related, but I occasionally run in to a situation where a whole section of a tech will not allow me to place a block at all. It just shows red, but if I remove all of the surrounding blocks and replace them I can usually get it to work again, but it's very time consuming.
