Very well. Thank you for your reply and hopefully this information is helpful.
Viewing post in How would I do this? (Q&A Thread)
Addendum:
Apparently, Visustella Core plugins (this is an MZ project(!)) cause a weird arse "cannot read property of undefined" (IsPressed); this occurs whenever attempting to go into any added menus. Only using VS Core and VS Skills States Core.
Could use YEP plugins; pretty sure FOSSIL holds those steady...(?)
