820: Internal error
What it means: Our service failed for an unpredictable reason, for example the response from the exchange’s API was garbled.
What you can do: Wait and try again. If it happens repeatedly, please contact support.
So I did. The answer is a measly copy&paste:

Hello,
We understand your frustration and appreciate your patience. We're very sorry that your orders were not executed within your expectations. We recognize the trading engine issues during periods of high volume, and are hopeful that the new trading engine being implemented will help alleviate the problems. Though we strive to offer the best service for our clients, performance can never be fully guaranteed. This is the risk of electronic trading, especially on an online platform.
Please let us know if you have any further issues.
" This is the risk of electronic trading, especially on an online platform."
Yes, but you faggots forgot to mention that you hereby shift the full risk to the customer. Why am I paying a Kraken Fee again?
I will transfer my funds again away from Kraken and after that I hope they go down the drain. What good is it if you know when to trade when Kraken doesn't let you and then mocks you with "the risk of electronic trading".
Fucking morons. No, that's the risk being on an exchange that had their system implemented by chimps.
