Dont disagree that it should be fixed. But as a work around, the simple approach is just to type in your talisman and then load it on the char. It doesnt disappear then!
Also, Im not getting a heap of lag tbh. A little slower perhaps, but for me, the search on characters is still only 20% of the time it would have taken me to scroll through 400 odd characters to find the right talisman!
