I got Desktop Dungeons on steam. Today I tried playing through the website, on a different pc, for the first time. It loaded my kingdom fine, and I beat Complicated Tasks part 6.
However when returning to the kingdom screen, I got an error message "There was an error saving to the cloud". Retrying did not work. I tried quickly entering and exiting a dungeon to force a different save, but had the same problem.
Later on today, I got on through steam, saw that I had lost that progress (I suspected as much) and once again beat Complicated Tasks part 6. Going to Kingdom screen it said my local save was different from my online save. The local save had CT part 6 done so I selected it. But now the "There was an error saving to the cloud" error comes up after every save. Cloud saving appears to be totally wrecked. At least my local save works...
How can I fix this? How can I play through the browser without causing this semi-permanent cloud save corruption?
