Hound wave causing server disconnect

[ptwhisper]

My current local singleplayer server is disconnecting me from the game at the beginning of a hound wave. The master server log has the dump

so it looks to be some sort of problem with the hounded.lua. I've disabled all my client mods and validated game files to no avail. My two server mods are Wormhole Marks and Health Info, which shouldn't affect hound waves. Is this an issue I could fix by manually editing the hounded.lua? Or is it something more involved?

Try disabling all mods to see if that works.

If it does work, you'll have your answer, if it doesn't then at least everyone trying to help is not bothered by the fact that it could possibly still be related to any mod. :P

If everything still doesn't work, you can try a fresh installation. Some people have had decent success with that.

I've disabled server side mods as well, as well as reinstalled. The issue persists and the master_server_log dump remains the same, so the issue seems to be somewhere in the save itself.

[Daniel86268]

Well, as it seems there was a bug with loading worls with pending hound waves that they fixed an hour ago. This could be what happened to you.

See if it works with the new update.
