Maybe most of them, including me, are stucked at some building and refuse to pay ME to get out of that situation.
Why should players pay for a glitch reintroduced with a VU done by MA.
The falling through ground at buildings bug, is not new. We had that several times in the past.
Got fixed got reintroduced got fixed got reintroduced, got fixed got reintroduced again.
Hell, MA check your code for old known bugs befor you send upgrades online.
