ok then. I've got an issue with the consignment store registers, initially with both the elixir store register and the general consignment store register, but now just with the elixir store register.
It is the issue with the registers or the register operator not opening up the buy/consign screens when you click on them. As I own the Consignment Store (the Landgraab's one) I went in there, deleted its consignment register and added in a fresh one. That fixed up the problem with that register. I also put an elixir consignment register in there on a spare bench. I click on the register/operator and select buy. It remains in the sim's queue for a few seconds and then drops out. I have saved the game, exited and returned to the game, but the elixir store register in both the elixir consignment store and the general consignment store have that issue.
What else should I try to do?
