Bagnon recently had an API update, so now ReagentBankButton has an error on load:

46x Bagnon_ReagentBankButton/main.lua:158: hooksecurefunc(): ListMenuButtons is not a function
[string "=[C]"]: in function `hooksecurefunc'
[string "@Bagnon_ReagentBankButton/main.lua"]:158: in main chunk

Locals:

Thanks for the info! It turns out that from Bagnon 10.2.10 on, it implements its own Reagent Bank Menu Button. Thus, this plugin here is no longer needed I would think. :-)
