I believe I have found two bugs in the Erosian War section of the calculator (Great Thenours War). I have no idea if these bugs are specific to me for some reason or affect everyone, or if these have been reported before. so please ignore me if these are known. I have verified my own game files as having the correct numerical values as well as using Thosha's guide for my run. The calculator I am using was the one released on March 23rd, v0.17.0. If the calculator I am using is out of date please inform me. All that being said I am kinda stupid and prone to making mistakes. If this is a problem of my own creation please inform me of that as well.
The first issue is that 1 Tower Front point is not calculated at the Tower Crossroads 4 section. According to the wiki when you choose to "invest mana" and Xestris reveals herself you then gain a temporary ceasefire with her, and in addition to 1 Xestris RP you are supposed to gain 1 Tower Front point as well. The Tower Front point is not recorded in the calculator. That being said this does not stop you from getting the highest score for the Tower Front if all the rest of your decisions are correct, this is probably low priority.
The second issue I found was that the calculator incorrectly counts how many Incubus King items I have. According to the calculator I have 4 items (Armor, Helm, Shield, Pin) but it only counts 3 of them. This leads to Tanurak Strike +1. This turns Tanurak Erosia switch On, and reduces the Front by -2. Since I have 11 Captives, it only reduces the front score by -1. Following the other decisions in Thosha's guide this ultimately leaves the Erosian Front score at 28, 2 points shy of the necessary score for Esthera to have a War Satisfaction of 5, which gives +15 Orgasmic Empire and +9 Esthera RP. If that was all it did I wouldn't complain but it messes up the decisions that Esthera is allowed to make post Incubus Prison section, which is originally how I came across this.
