Needs second pair of eyes, they appear in crash logs here and there. Its
merely a patch on a open wound.

As in aslong there multithreads in mapupdate, which we need for decent
performance and core calls are not done correctly due various reasons.
These type of issues remain.
Although i am planning to experiment a little with threadsafe execution
of our strategies vs performance.
The most effective thing we could do is check every single action and
check its stateless and where it does effect the state or read the state
of a core object its done in the safest way. flags, worldthread where
possible and/ot simply taking into account the state might be invalid.
