the way you describe it, it seems not a bug, but a problem with transportation. As your economy gets bigger, you need more and better roads, else transportation collapses. Just like in the real world, actually. then wares are not delivered anymore, which cranks down your economy until the lack of newly produced resources clears the roads a bit...
if you have a lot of wares waiting at the flags, then you are misnanaging transportation. try to set up multiple paths for the wares to avoid chokepoints, try to completely avoid 3-step roads on main routes because even just one of those will be a chokepoint. ultimately, transportation is your main enemy when you get very big
I have no 3-step roads in the main transportation routes.
And it is not a bug when there is a fish at a flag, no other wares around and no worker carries the fish away?
I know, that transportation is key for a large and running economy, I always build double-roads for main transportation routes, try to avoid any building being directly connected with these roads (at least one 2-step road away), try to build warehouses where they are needed and split different resources between nearby warehouses to avoid a chokepoint, ... I think my transportation system is pretty fine- also if it is not "the best". But the wares are not transported for hours, even if there is no chokepoint anymore.
Yes, maybe. Was it a loaded savegame or a new game which you played without stopping and loading? And do you play with release candidate 20?
I saw the bug some days ago several times, we all had version rc20 or bzr9043 or something like this. One time it didn't even help to switch the wares at the construction side, and it didn't help to rebuild roads neither.
I had to load the game several times- because I don't wanna play for days without a break and there is also another bug/nonconformance I have found no suggestion for that forced me to reload (but we should stay at this topic, the other thing is for sure not connected to that, it was just a problem with ingame controls)
there is a limit for wares at a single flag, isn't it? But when I read through the other descriptions of the bug I think the wares are realy there, therefor they count.
The reason why I ask this: if there are more wares at a flag that are not transported anymore the flag will be blocked somewhen.
There is a known bug that sometimes a ware loses its destination, and we haven't found it yet. It's hard to pin down, because it happens pretty rarely.
is there any suggestion how to give these resources a new destination? And additionaly: do they still count as "on the way" for there destination?
Because some buildings do not get wares for building up or work I think they still count there, otherwise there would be another ware that takes their place and would be delivered.
A workaround would be to delete all wares without destination after 10 seconds, wouldn't it? Then the ware does not exist anymore, the building calls for a new one, the road is cleaned.
But for this "solution" I would suggest to make it optional, so there should be a tick in gameplay options with the hint "if you activate this you might also loose some resources- but your roads get cleaned up". If just make such a check/cleanup when loading a game, then you also can see if the bug still occures..
If you want me to help you with testing just let me know.
