"Custom periods" in the adjust variable are not upgrading correctly. The current version upgrade script on the version-upgrade-updates branch has a debugging msgbox showing the issue. There seems to be an issue switching between different matrix types, [ [x,y,z] ] and [ [x], [y], [z] ] for the adjust_periods variable.

Using the attached .sam file (created in SAM 2022.11.21), see that the "custom periods" loss is not upgraded correctly.

Once this is fixed, code needs to be updated in the version upgrader script in 3 places, currently lines 71, 104, and 114, which is all the places that the adjust_periods variable is set.
