SERVER ISSUE: Crash due to CultureManager get SortedWorks

[Thibault-Brocheton]

Server Version: 0.10.0.1 beta release-535 No Mods

French server with 2 active days, around 100 online citizens

Steps to Reproduce:

Some citizens created WoodenFrame, added pictures inside and gave culture points After a server restart, server was unable to start because of following error:

[22:57:06.571] [21] [Error] [Eco] Failed to start the server. Exception was Exception: NullReferenceException
Message:Object reference not set to an instance of an object.
Source:Eco.Gameplay

System.NullReferenceException: Object reference not set to an instance of an object.

Here is the map to reproduce it:

Deleting WoodFrame from the save game does not fix the issue We had to rollback and ask players not to add woodenframe in the world. We're waiting for your advice to allow them again

The initial crash we had was linked to Twitch extension:

System.IndexOutOfRangeException: Index was outside the bounds of the array.

We disabled the extension, there's no more crash, and now we don't have the culture crash at startup anymore.

Crash has been addressed long ago, cause for why picture was able to be created without creator is still unknown and not reproducible so far.
