Dungeon Architect

Hello, I just installed the plugin, and Im following the Quick Start Guide, in Engine 4.19.2. Im in the **Level Authoring by Players (Runtime) **but when I hit play I get this message:

One or more blueprints has an unresolved compiler error, are you sure you want to Play in Editor?
BP_DALB_GameState

When I open the game state it says the pin Cell Location no longer exists on node “Add paint cell” and “Remove Paint cell”.

If I choose to play anyway the game open but does nothing… What could I do?
