Thank goodness I'm not the only one struggling with this problem. It happens most when there are a lot of plates, and more often with plates later in the series. For example, if you have plates 1-9, plates 7,8, and 9 are most likely to have parts that are shifted. It's not a consistent bug, but it is very common.

It's been happening for a long time in the daily builds, it didn't just happen in the RC. I am on intel Mac platform as well.

Same issue present in 2.1.1 for me. Seems to only have shifted the final row of plate content.

This is becoming rather annoying. It's not only the bottom row, it's all of them and AFAICS they move by a length of n*m, where n is something like 10mm and m is the row number, starting with 0

Can confirm this is happening in WIndows as well with v2.2.0

It is very annoying for large projects.
