Mesh Assert in unknown file and line 0 (probably a flash related issue)

Hello,

I am getting error -

t:      17532>, app_error_weak.c,  108, Mesh assert at 0x0002CF9E (:0)

I debugged it, it took me to the flash_manager.c - line 254 which is

NRF_MESH_ASSERT(p_manager->config.p_area[i].metadata.page_index == i);

Any help is appreciated.

I would like to point out, i am not getting this error on all dev kits, on one of the dev boards, it got provisioned.
