MudChip: Fix memory allocation

[ScarletKuro]

Description

Fixes: #10911

Additionally, the ObserverManager has been improved. Technically, these new methods should prevent dictionary copies, unless the ConcurrentDictionary copies the dictionary on its own when Value is called to avoid collection modified exceptions. However, I’m unsure how the ConcurrentDictionary is implemented in this case.
