Please delete any unfinished 4x4 patio blueprints you have on your claim that were placed prior to patch va2.2.1d.
Just a heads up. The bug with the 4x4 patio door was fixed in the latest patch. However, old unfinished 4x4 patio blueprints that were placed prior to the fix are bugged beyond repair. If you have an unfinished 4x4 patio blueprint on your claim from before the patch, please delete it and place a new blueprint.
Patch 2.2.1d was deployed on Thursday 16-4-2020.
