Yes, bash will not remember paths across reboots.

Bash optimizes lookups on the PATH; having found an executable on PATH
once, it can remember that location for a minor speed boost.  The only
problem with this is that the cache can go stale.

From what I understand remembering locations is usually done manually by
running “hash”.  I don’t know what would trigger this behaviour in your
case.
