Great update, haven't found any glitches yet. but I do have some future improvements to recommend.
The dialogue during intimate encounters with player character weight gain turned on does not reflect the weight of the player enough. Example, my character became immobile but in the intimate scenes with the carer my character was still mobile.
I think the game still needs more dialog variety, the improvements you have made so far are a good start though.
Another improvement would be a mechanic where the player can play with/explore their gowing fat body.
I think higher weight stages should be added for more late game content, right now once characters become enormous there isn't that much reason to keep going back to them.
