I’m not the only one running into lag problems.
Redditis rifewithpeoplereportingissues, and it seemseveryone at Kotakuis having trouble too.

I’ve got no problems with the location itself.
I do hope developers Second Dinner don’t run out of steam with good new location ideas.
That said, the location that fills your deck with rocks is awful and I hate it.
