Losing an item while Making Materia

So I was SBing some spears trying to get some Crit4 materia this morning. I was in the process of converting one to materia, and I got attacked. The animation interrupted, and I lost the weapon, but I got no materia out of it. Now I know I shouldn't have been in an area that I stood the risk of being attacked while converting it, but has this happened to anyone else? I'm just trying to see if its a glitch, or if it was just my bad timing that lost the weapon. Thanks in advance :)

yep just like if your crafting and get attacked you loose your mats and get nothing. its no glitch its just the way the game engine works.

Alrighty, Valmonte, thanks for that. Bad, Jojo, BAD!
