Endless Loading: custom_schedule_data_classes

FoxnMoon​ Could you post the entire LE without any mods installed ? Including BE. The error should be in the doc folder without the mod too. BE just interprets them.

The others all don't have an LE so yours is potentially different.

Make sure to either upload the LE somewhere else and link or c/p the content.

Thank you Crinrict, I hope you're well paid for everything you've done for us all for so many years.

Here's the copy-pasted LE; it's going to take up a bit of space.

Hi FoxnMoon​ 

I split this into it's own thread. Don't think it's the same.

Bit unsure what happened to the LE post itself you posted. It's not showing up for me in this thread. Might be just a display issue though. 

Would you be willing to share your save with me ?

If so, upload it somewhere like dropbox, googledrive or OneDrive and PM me the link.
