I was debugging smuggelers when I had to leave. Version: bzr8820[bug-1751440-smugglers-desync-single-coroutine] Host was on Windows-10 , 1st client on Windos, 2nd client on OSX, 3d client on OSX.

For some reason OSX Computer froe, and was coldstarted by my son.

When tryinf to restart the game I got some strange messages, I assume the savegame was broken?

(by klaus-halfmann) Played one of the savegames with OSX as Host, kaputtnik playing 3d and 4th client on Linux, had no such Issues. Looks like I must spend a debugger-session.

(by klaus-halfmann) Argh that savegame is not compatible with trunk:

map objects: [/Users/klaus/develop/widelands-repo/trunk/src/logic/map_objects/immovable.cc:769] immovable type: tribes do not define immovable type "resi_gold1"

maybe this is the reason for these logs?

found "on ": parameters = "failure fail" read handling method for result 1: 0, parameters = "", reached_end = 1 found "on ": parameters = "failure fail" read handling method for result 1: 0, parameters = "", reached_end = 1 found "on ": parameters = "failure fail" read handling method for result 1: 0, parameters = "", reached_end = 1 found "on ": parameters = "failure fail" read handling method for result 1: 0, parameters = "", reached_end = 1

OTOH perhaps the network game wanted to report this, but failed as of some other bug.
