OK, I think I see the problem here. bootMer is able to handle
offsets correctly when they're written in the form
y ~ x + (1|f) + offset(offset_term)
y ~ x + (1|f) , offset=offset_term
(I so rarely use the second form that I forgot to check it -- I think
this is just a hole in bootMer).
Can you see if that fixes your problem?
Meanwhile, I will add a Github issue.
