[491] Building a household/fort makes client to crash

[servia]

Thank you for creating an offline server! I don't like PvP so i couldn't go up to lvl 45 in official game.

Version: 491 SPP [SinglePlayerProject - Conan]
Steps to reproduce the crash:
1. Create a guild
2. Buy some fortress
3. Go to a node and build a fort
4. Open the map and mouse over any node -> client crashes

Loggining again doesn't fix the issue, the only workaround is to remove the fort entry from gameserver.households collection.

Is there any fix for this? Is there any better client/server than the one that i'm using?
