Hi, it's not simple to reproduce this, but it's happened already 6 times in last 10 days.

Issue is at server!, players fighting with NPC ships, and sometimes NPC or players ramm each other.

Now players have landing gears pointed forward to catch the npc ship and to grind it, so when that npc ships smash at high speed in too player ship, both ships merge! SIM is dropping to 0.2 and after few sec they bounce and when they do, landing gears trying to attach! but for some reason there is a fail there.

Also this can happen when player traveling with high speed and cant stop and smash in to voxel or other base, while landing gears point to that vector and have auto lock enabled!

So ships crash and bam, server crash.

This error in logs.

Here one more right now.

New information!

Player reported that he thinks that server crashing when he is changing active safe zone range and other ships inside the safezone attached with landing gears.

Last 2 crash came from this change.

I have disabled all landing gears in that safezone and no more crashes.

The same problem, it happens several times a day

Same bug
