We want to upgrade our guild hall to rank 4 to enable building upgrades to rank 2. We currently have a rank 3 guild hall, a lumberyard, farm, mill and quarry as well as a market, plus one open support plot. We can't set guild hall rank 4 as contribution target, the button is disabled. However per description we fulfill all the requirements?
Do we always have to fill all open plots before we can further upgrade the guild hall?

Rank 4 description contains no additional requirements, simply says "Coffer capacity increases. Structures can be upgraded to Rank 2"
As I wrote in the OP we definitely have 4 "other structures" (in fact, we have 5), so I'm at a loss
EDIT: While your at the signpost, hover over everything to check "have vs need." If something's exactly at the "need" marker, add one to the coffer. There might be an alliance discount rounding error coming into play too.
At the time we were wondering if we needed PvP - but it wasn't that.
