In this case, the character is a Monk for the first 6 levels, so the so the first ASI at 4th level is correct. However, as the 7th level class I took 1 level of Rogue (Monk 6 / Rogue 1), so the next ASI does not show up (correctly) until level 9 (Monk 8 / Rogue 1), and at Level 13 (Monk 12 / Rogue 1) I took a feat. In the ASI&Feats (Start page area 5) they are listed as Level 4, 8 and 12 which is somewhat confusing due to "level" referring to both character level and class level. I believe ForgedAnvil is fixing this by changing the "level" to the character class in 1.59. The issue is in the "Race, Background, Class and Feats" area, in the "Ability Score Improvements & Feats". The ASIs are noted as being gained at levels 4 & 9 (the correct character levels in this case), but the feat is noted as level 12 which is the correct class level but not the correct character level. I believe both the ASIs and Feats should show the character levels at which they were gained, not have one show character levels and the other showing class levels, that is all.
I see on the Start page a section "Additional Details" which I was thinking would be useful, but I see no way to actually enter data here. What am I missing?
