I do use high-priority map. But basic bindings like C-x C-c, C-n/C-p, etc are in the global map. Also this bug causes all those keys to be totally unbound. So it's not as if a high-priority map is masking a global map key. If it is unbound, it is unbound in both high-priority and global maps, right?
Next time this happens, I'll see if my high-priority map bindings are intact. To prepare for that, I will bind C-h l to the high priority map too so that they work even if global map is wiped out (there's probably no point binding M-x, M-:, etc in high-priority map because the self insert bindings are wiped out too).
