Looks like remapping will be needed

Here is what was deduced

[1494] = { total=3, base=1, parent=1527,altid=nil, remap={ 1, 2, 3 } }, -- ToS1: The Gates of Hell (6/27/17)
[1495] = { total=3, base=4, parent=1527,altid=nil, remap={ 1, 2, 3 } }, -- ToS2: Wailing Halls (7/11/17)
[1496] = { total=2, base=7, parent=1527,altid=nil, remap={ 7, 8 } }, -- ToS3: Chamber of the Avatar (7/25/17)
[1497] = { total=1, base=9, parent=1527,altid=nil, remap={ 9 } }, -- ToS4: Deceiver's Fall (8/8/17)
