Hideout instance crash

Hi,

I would like to report hideout instance crash.

Steps to reproduce:
1. Get Niko quest-chain in map
2. Open portals and jump into map
3. Take first Sulphite stack
4. Leave map by setting up new portal/return by previous portal
5. Go to Azurite Mine
6. Buy some voltaxic sulphite capacity
7. Return to map and complete it
8. At this point portal is broken, you can't return to hideout.

Thats all. I got this crash twice with the same conditions.
