[2019] PSA: Don't use Large Cannons yet

Investigating

Update: We have a fix incoming for the issue where Large Cannons were being destroyed when Gunports were demolished (or destroyed). The build is approximately 20 minutes away. We recommend not placing Large Cannons down if you haven't already, as they will still have the issue. If you have placed them on gunports, you will need to demo them and place them again to avoid their destruction when the gunport is demolished or destroyed. My apologies for the inconvenience folks 🙇

Update 2:

Fix is now live.
