Recently been encountering the Out Of Memory issue more often server-side, as many have before; as the modding community gets more creative and expansive, this problem gets more common. The game just can't handle what the community is coming up with.
It's been stated by a dev in the past that a full 64-bit game client upgrade isn't in the cards due to not wanting to raise minimum specs.
But, would a separate 64-bit server be considered? It would help alleviate some of the growing issues, at least.
