415 bugs and observations

[Marabekm]

I've recently discovered a rather alarming issue while working in the FMB of version 4.15

I have noticed that on several of the Pacific maps, I am unable to insert moving ships on large areas of the the following maps:
Marianas
ChiChi Jima
Guadalcanal Early
Tarawa
Coral Sea --- The worst. Can't place ship anywhere
Iwo Jima
Palau
Wake Island

I didn't have any issues like this in 4.14. Seems like I can only place ships fairly close to the land masses. Large areas of water farther out simply won't allow me to insert a moving ship. Coral Sea is the worst because there is no land.
