Can you submit that issue over at our Git? It is the fastest way to get a problem in front of a developer.

Dies ist ein seltsames Problem, und es kann schwierig sein, alle Änderungen zu ermitteln, die seit dem letzten Anmelden aufgetreten sind.
Ich würde vorschlagen, zur offiziellen Zwietracht zu gehen und dort um Hilfe zu bitten. Es gibt Leute, die dir helfen können. https://discord.gg/eco

That is a weird problem, and it might be a bit hard to track down with all the changes that have happened since last time you logged in.
I would suggest going to the official discord and asking for help there. There are people there who can help you.

I'd submit a bug report including this information over at https://github.com/StrangeLoopGames/EcoIssues.

We have actually been working on an overhaul of world generation for a while and one of the many improvements it will have is the rivers with more typical banks. World gen will be in 9.0.

Can you get in contact with us at support@strangeloopgames.com so we can track down and fix some of these issues?

Thanks for letting us know about this. Could you report this bug using these guidelines? http://ecoforum.strangeloopgames.com/topic/81/how-to-report-bugs

At the moment offline play only works through steam. We do not currently support off line play through SLG, maybe at some point in the future.

Actually it's F: We thought this was a thing that was already in the game.

Could you ping us on discord or open a bug report so we can troubleshoot this? A couple of us just tested running the game without an internet connection and were able to get into a world without trouble so either you are doing things slightly different than us or something hinky is going on.

Mods sind außerhalb meines Wissensbereichs, aber ich habe gehört, dass sie sich besser integrieren, wenn du mod.io verwendest (https://eco.mod.io/) Bist du zur offiziellen Zwietracht gegangen und hast dort gefragt? Es gibt einen Kanal für Mods und Mod-Unterstützung.

Mods are outside of me area of knowledge but I've heard they tend to integrate better when you use mod.io (https://eco.mod.io/) Have you gone to the official discord and asked there? There is a channel dedicated to mods and mod support.
