/admin scan grids throws error

[tbankstemp]

Essentials version: 1.13.6.93
Extender version: 1.131.7.293
I know you said grid scanning is mostly fixed, so, just a bug report :)

Same errors thrown with "/admin scan grids" and "/admin scan grids noownership" or any other scan grids options.

Thanks for all your hard work Rex!!!!
