Can you give a few more details of the crash, the ‘endless jumphole’ is my personal favorite.

Well - there is a max limit to the amount of stuff in systems according to Giskard, but i have had at least 3 jumpholes working at any one time. If you copy and paste some of the jumphole entries here, along with the end entries to the other systems - and also the systems_shortest_path.ini entry and shortest_illegal_path.ini entry - then we can help narrow down your probs!! Otherwise its just pissing in the dark when your surrounded by angry tramps sleeping nearby - chances of hitting the specific spot that won't get you done over are slim
