Well, I work on similar issue - but not related with land ownership - all land is conquered in vicinity. Two ports in kind of bay very close to each other and it crashed when second one was finished. I found out that second port tried to place its portdock over portdock of the first port (at least partially).
The problem is in Map::find_portdock() function. Each field to be a portdock field should be tested: a) for other immovable already there (= other portdock as we are in water) b) ownership of such field (not problem in my case, but can be a problem in your case) Regardless of this branch I think such check is really needed... -- https://code.launchpad.net/~widelands-dev/widelands/ship_and_portspaces/+merge/285409 Your team Widelands Developers is requested to review the proposed merge of lp:~widelands-dev/widelands/ship_and_portspaces into lp:widelands. _______________________________________________ Mailing list: https://launchpad.net/~widelands-dev Post to : widelands-dev@lists.launchpad.net Unsubscribe : https://launchpad.net/~widelands-dev More help : https://help.launchpad.net/ListHelp
