That's funny. Error code 0 means “no error”. Haha. This is obviously not the case here.

Can you please do the following when this happened again?:

1) Post screenshot of exact error message.
2) Post the last 50 lines or so from game0.log.
3) Post the name of your operating system (e.g. Windows 7 or Ubuntu 19.04).

You find the file “game0.log” in your user directory under “Logs”. This is just a text file, by the way. It tells us what happened before the game crashed, so it's very important to us.

Also, does the error persist once it happens or is it only sometimes? What happens after a full restart of Hedgewars?

Thanks for your help. Thanks for your time to playtest Hedgewars. It really means a lot to me.

Alright, let's see...
1) I couldn't figure out how to add a screenshot, so here's the exact message: Unable to run engine at C:/Users/Hedgewarstricks/OneDrive/Documents/Hedgewars 1.0/Hedgewars-1.0.0-Alpha/hwengine

Oh, the Hedgewars text smilies are all these: 0 _ 0 (you probably knew that already, but anyway...)

3) A windows 10 pro

Okay, so once the error comes up, I can't fight on any mode at all. Even after I restarted my computer, it didn't work. However, if I uninstall, reinstall, and unzip the file, it will work, for a while again.

As for helping? Of course. I love this game, making playtesting really enjoyable and fun. And you can bet that I will continue to help

Ah, thanks.

I have looked up the error message again and I was wrong. For this particular error message, the error code means the following:

I also noticed you appear to have Hedgewars installed in OneDrive. That's a problem. OneDrive is somewhere on the Internet … In other words, whenever your Internet connection has a hiccup, you can't access the files there. That would explain why starting Hedgewars only fails sometimes, but not all of the time.

Try installing Hedgewars on your own harddrive instead. Hedgewars only takes about 200 MiB of storage space.

Personally, I don't think it's a good idea to install your applications on some remote computer you don't control (which is what OneDrive basically is). I don't know if OneDrive was even built for this.

Hmm, alright, I'll try moving from OneDrive and telling you how it goes
Oh, when I reinstalled hedgewars 1.0, I tried a random battle and got a 3v3. This means that the random team works

Nice to hear. Please report back when you stumble upon any new bugs. Thanks.
