It's a long list, but hey, authenticity yo.

Are there any tricky things testers should keep an eye out for?

• No
• Yes, as follows:

I don't have much to say other than enjoy the quest!

Dad should have a "second" attack where he swings his big stick and smacketh players to fuckall corners of the arena, but I don't know how to code this.

• I have tested these changes thoroughly.
• This requires extra testing due to changes to architecture or other similarly risky changes.
• I used the Thanos Tool for any JSON edits where possible, and have attached screenshots of any changes.
• I acknowledge that this contribution will be released under the AGPL license.

*** NOTE: If Gitlab complains about pipelines stating that you need to "Validate your Gitlab account" there is no need to worry. You do not have to do this and it is only occurring because OUR pipeline tried to run on your fork. While it's preferred that you do validate your account, you can safely ignore/dismiss this message from Gitlab. ***
