[2020] 3 artefacts excavation sites were balanced well btw.

It depends what you consider a 'fix'. It is intentional that you don't get a complete 1:1:1 ratio.

I did however make changes so that we remember the last 5 artefacts that you've discovered (currently we only remember 3) which will help with the 3 artefact excavations. This is set to go live next week.
