this isn't quest related this happened after my 4th visit to the shop the 3rd visit was during the sick village quest but that went smoothly, its the day after and I was heading there to buy some mana stones and the Error Code pops up unable to Read. wish i could copy or take a screen shot but doesn't let me. it reads as follow (typing it out a litle)
TypeError: Cannot Read Property '_objectives' of undefined.
it gives a list from there if need me to type it all out i don't mind if you need me to that is. the Only thing i can do is close windows than reload from there I try loading a older save and it pop up again, and when that happened i did a uninstall and reinstall of the game, still pop up. so i'm not sure if its game or save that's corrupted with that Error but after just trying out with a new Game just now as typing this, it still came up and on the first visit.
