I seem to have finally restored the reliability back to how it used to
be, it seems the crux of it was the Excel sheet reading for Items. I
moved the parsing to the start-up instead.
Instead of standalone functions in the common module to perform game data tasks,
there is now a shared GameData struct that these functions moved to. This speeds
up a few things, and can take advantage of Physis' built-in index caching.
I know the current solution isn't ideal (each connection has to mutex lock to
access gamedata) but it's at least better than before.
