Item Fusion gone... Wrong?

Are you sure they're fused? I don't see a "crafted by" tag.

Try to check the data/extractions. These might be a special, "prescrolled", version of these items?

They're indeed fused. The title at the top says "Soul Shooters and fused weapons."

I tried fusing a low level Katana and it came out with 0 slots as well, but it was given Magic Attack and Accuracy - stats it didn't have before. I'm thinking something went wrong within the past few updates. My level 90 warrior gear set was all results of item fusion, and those had slots and were able to be scrolled with armor for STR scrolls.
