Before you go, omfg. First of all the distances between the holes is really short like 20-30 K with two exceptions. 2 - 4 minutes flight time.
About the dangers, I placed invisible radiation fields in the system with two layers. One will warn you and the core will blow you up.
To the rest of the update.
-Fixed now the reputations between the Sairs-Bundies-Unioner NPCs
-Even more NPC fix (Removed GB patrols by the Munich Gate in Frankfurt and the same with the Frankfurt Gate in Munich) Also, reduced Gate Population a bit.
-Moved a few JHs for short traveling time
About removal of the systems.
It is your decision, just fly through and ignore it..or go find some surprises.
