While editing a map the foundry tool suddenly started to experience a MASSIVE slowdown of information transfer (sliders on the map stopped working). Positioning stopped working, the ability to adjust map size while viewing it stopped working. Unable to switch from one tab to another w/o it taking three minutes (literally).
This all started happening about 15 minutes ago.
This was due to an accidental placement of an object outside of the map, basically freezing the foundry tool and not allowing me to place the object correctly.
