Activating beacon effect crashes the game to desktop, when player opens inventory for a first time.

What I expected to happen was...:
Activate beacon, open inventory to check the effect if it's working or not.

What actually happened was...
After pressing inventory button, game crashes to desktop

Tried with 3 and 4-tier beacon pyramid.

Steps to Reproduce:
1. Construct a beacon pyramid
2. Place beacon, choose effect and power it. (In my case: Haste at fistrs, Haste II later again)

3. Open inventory... crash.

There is a workaround: to get it to work:

1: After beacon activation, wait until your world's autosave kicks in.

2: Open inventory - game crashes.

3: If you have waited enough, your game will be autosaved after beacon activation and the effect is working as usual. Open your inventory works as intended. Happy playing!
