Shattered Kingdoms

Are eye washers supposed to have a limited number of uses? If so, why not make them disintegrate or in some other way indicate that they no longer work?

Currently, there is no echo when trying to use an expired eye-washer and no way to tell if an eye washer is expired unless you are blind.

I tried searching the board to see if this is mentioned somewhere else but could not find any information.

The eye-washer NOT WORKING is not indicator enough that you should toss it?

Any chance to make them work like drinking containers? So that they could be refilled.

If there were an echo that said, "The eye washer fails to wash your eyes" then I would agree with you, but if the game just doesn't respond at all, then it looks like it could be a bug.
