Need help : Locked in "Things Done Changed"

[Chronepsys]

This topic is about one of the ending so it may spoil if you did not end with the phantom liberty solution : cured by the nusa.

 

I am stucked by a bug when i am going to meet Viktor, entering the Zetateck store, the two npc do not react and do not give me speach option.
So the door remain closed and even if i open it with a mod, Viktor do not react.

I tried with a previous save, before starting this quest with no change.

Is somebody know something to do please, i really like to play this ending.

 

Thanks.

While looking for solution, i found that the issue may comes fom something weird.

the door of the zetatech is missing so i cannot open it and i think that does not start the npc action.

However, i don't know what to do. I just checked my files.
