Switch bot to do novice missions only and run for a while with cheap fit (tristan, t1 drones). Bot will create missing bookmarks. If some of bookmarks appear too close to complex, bot may die. Sooner of later all systems became bookmarked, complexes change locations and bot will use bookmarks w/o problems.
A problem with initial bookmark creation is known. But better to avoid another outcome when bookmark are placed in the grid with stargates.
Check your default mouse speed and
delays. Faster settings on screen are OK for not virtual machines.
If you define safespot BM name in settings, bot will use it. Report in case of a problem. I tested with standard names only.
