Works perfect. Thank you for taking the time to look in to this!

I'm guessing it's something I accidentally caused with my mod mix-up?

I have mods installed but disabled them all for this world - both for creation and playing it - only Essentials / Creative / Survival 'mods' are enabled.

What's odd though is I see calls in the log referencing missing mods. Are mods still being loaded into savegames even when not enabled? The 

client-main.txt

30.9.2019 16:44:05 [Error] [Armour_Release_V0.1.6.zip] File 'ArmourMod.dll' is not in the mod's root folder. Won't load this mod.
30.9.2019 16:44:05 [Error] [CarryCapacity-0.4.1.zip] File 'CarryCapacity.dll' is not in the mod's root folder. Won't load this mod.
30.9.2019 16:44:16 [Error] [VS-1.9.6-TheNeolithicMod-1.7.2.zip] File 'Neolithic.dll' is not in the mod's root folder. Won't load this mod.

Okay so I realized that there is also a  'mods' folder inside 'VintageStory', not just 'VintageStoryData' that mods are being pulled from. Somehow I had those 3 mods in there. These mods are not shown on the in-game mod selection screen so never appeared enabled, and these mods were not active in this world, ie none of the blocks/recipes. Is this a potential cause?

I tried moving the VintageStoryData folder, removed mods from VintageStory folder, uninstalling, and doing a fresh install of 1.10.15. I copied over the savegame and playerdata folders

Loaded in and... same client game thread crash.

edit: client-main.txt attached (after complete reinstall)

Thanks for taking the time to look at it

Here's a download link (900mb) - https://drive.google.com/open?id=1FONBFcX4z6LhtgvCmk3h1Y7LHzy-v2BI

Have 40 hours into a save and now I get this message every time when trying to load in -

'Whoops, a client game thread crashed, please check the client-main.txt for more information.'

Any way to recover / fix the save?
