I love the new update! There seems to be a problem with the scene after you approach sans for food and he kills you (in the route where you romance both sans and papyrus), after that scene you can't progress anymore (during the scene where you meet the ice cream stand guy). In this same pathway choice, if you approach sans and get killed but continue, it forces you back onto the friendship path despite romancing both Papy and Sans. Other than that, I think it would be so funny if you can romance all three of the Gaster brothers. XD
(First Picture) This is the scene where you make a decision on whether you want to go to the ice cream stand or go to the city and there are no answers so you can't continue.
(END OF HOTLANDS) In the recap after you decide to go to sans which results in you dying, you get this screen where it says you are on the friendship route while romancing Papy and Sans.
