Dec 2020 Book and Quill Dupe

Background
At the end of 2020 the server was at that time 9 months old. Daenningas coded in a minor dupe into a plugin, which was expected to be a treasure hunt, the dupe wouldn't work everywhere and the details of the dupe were not published.

Unbeknown to Daenningas at the same time a zero day dupe was discovered which Paper (the software that runs the server) was susceptible to. The dupe involved using a Fabric client along with a special .jar mod file and a book and quill to overload player data saving. This dupe turned out to be extremely powerful as entire inventories could be duplicated by dropping the items in a chest, logging of and back in again, repeat.

The dupe was active between just before December 23rd, 2020 through to New Years Day (2021).

Dupe Stashes
The above dupe means there are likely now significant dupe stashes around the server. Similarly nether and overworld spawns were littered with blocks valuable to newer players such as Diamond, Netherite etc. To the players duping these blocks now had no greater value than dirt or stone as they had duped them in such high quantities.

Effects on PVP
Players now posses vast quantities of god gear within kits for PVP. Meeting up at spawn to brawl has become more common. Whether this is traditional 1.9 combat or Crystal PVP.
