If the abilities to spawn was removed while the CV is dead, and the CV has a time limit to live after its port is killed, then it respawns as the country who owns the port, both problems would be solved. Actually hunting a CV can be fun. We did it last week when the enemy hid our cv. We (Nightmares) sent out search patterns looking for it. We found it, but my B26s ran out of fuel about a 1/2 sector from it. So I reupped in B24s. The other guys made attacks as well, sinking the CA but the AA gunner was good and we had to work for it. The CV was 7-8 sectors from a friendly base. It took us 2 hours to get it back.
