Is the exp actually gone, or just disappeared off the bar, use "/exp" or re-log into the server, as when this happened to me it was a glitch where I had the exp, it just didn't display on the bar.

 

Same thing happened to me when I tried to combine a power V bow with an infinity book.

 

Mhhm, the first few times when I tried to combine an enchanted tool with a book, the exp appeared as it was gone, re-logging seems to fix it. A way to combine the items if you need to is combine a normal bow with the book, and then combine the two bows after that.

 

This has happened to me a handful of times. While the xp isn't actually consumed (just disappears from the bar, and can later be recovered by placing it in a sign and breaking it), it still hasn't let me do some important combinations, while making me lose time.

 

There is a solution to this: Whatever you're trying to combine, have 5 more levels than needed, and then try to combine.

 

While I have done this a couple times succesfully, it also has failed to me. Still, I wouldn't call it the best solution as on high-level combinations (i.e 39 levels), having 5 more levels would require a lot more experience orbs than absolutely needed.

 

Yes, but it seems this bug is purely combining tools/armor with books, which cost much less xp. For now, this is just a quick fix to help you get along.

 

I did this once and I only cried for 20 minutes! Beat that!
