The problem of ensuring that the right number of Orkuli work in a gravwell has been a recurring issue - the release version made progress, but still runs into problems regarding stars - so here's a solution:

Whenever an orkulus tries to jump to gravwell, it adds together the number of active (owned) starbases at the destination, the number of building starbases, and the number of starbases already jumping to that destination.  If it is a normal well and the total is more than 0, it cannot jump.  If it a solar well and the total is more than 3, it cannot jump.  Otherwise, it proceeds to jump.

Considering this, the code for additional starbases being disabled should be removed, as it would not serve any purpose except to interfere with other features.

The devs may have figured this out by now, but I'm putting it out there anyway.
