Summary0002350: AI may sometimes attempt to visit invalid boat object
DescriptionProblem occur that for some reason "validateVisitableObjs" called from VCAI::getPossibleDestinations don't remove boat object as it's kind a valid even if it's position completely messed up.

I'm attempted to reproduce it myself with normal client, but wasn't successful yet. E.g I have feeling that problem may occur because when hero in boat killed only "objectRemoved" for hero only getting sent, but that not explain why validateVisitableObjs not remove it as it's shouldn't be in gamestate anyway.

 So here is trace of that crash in "crash_11111.txt". It's for teleporter, but as far as I can tell what happen with boat is exactly same issue.

Also it's end up that first time when issue occur game crash on AI turn, but often when loading from save game start to crash on save serialization after AI turn is finished. Ivan also confirmed that saves get's corrupted.

 Just in case these crashes occur with "noncopyableBonusSystemNode" branch:
https://github.com/vcmi/vcmi/pull/148 [^]
So it's not simply issue related to bonuses, but there is likely something wrong happen in serialization or AI.

 Also I do have save files for these crashes, but they're only for noncopyableBonusSystemNode branch for commit d2341b9745eee9e271885a2524f6a12bde817e0d. It's also recommended to merge develop into it at least up to commit 9490a5d66d3d2506948521ffe91d6b844c254320.

Uploaded "CRASH_SAVE_noncopyableBonusSystemNode.7z".
