Hi, I'm writing about bug in DotA, not exactly in DiV so you can transfer this if I missed subforum.
I just played with Furion and I bought demon edge with my flying courier and made him carry it to me. When he got to me, item disappeared from courier but didn't show on furion (39:30). Here is replay so check it.
now here I read this a few times on some other sites, and it is possible that p is not a bug but if someone uses a script or similar devices such as hacks, and more may be a very confusing code maps and haks and created these things
