Yes, your membrane is drifting upwards (so the waters at the top get
wrapped around). You can restrain the membrane COM using the colvars
module, but I don't think this is worth the trouble (and the possible
performance hit).

Most probably. Resolvating would make no sense as you would have to
equilibrate a bit and so forth.

Do you have several different segments of water? In different segments the
resID can be repeated.
