I believe this is related to Jaliborc/Bagnon#2093

Sometime between Bagnonium 0.12 and 0.13, a BagBrother change made it so that even though I am using the default bank frame, right clicking when the default Warbank tab is open still deposits into the character bank. It is good to know that shift+right click puts it into the warbank, but with the version of BagBrother that comes with Bagnonium 0.12, this wasn't necessary with the bank frame disabled, as a standard right-click put it into the bank that was selected in the default bank frame.

I love this addon for its standard bag frame and guild bank frame, but the new bank and the warbank have too many slots to enable the bank frame for me. I'm not sure if this was an intentional change or an accidental one so I figured I'd bring it up. If it isn't something that can be fixed, I suppose I just need to learn new muscle memory for depositing to the warbank, but I made this issue in case it wasn't an intentional change.

Thanks for making these addons. :)

Didn't think about that. I'll add a check
