I had this awesome replay where I did this decap (did it for the march madness event)

The replay shows my opponent decapping me .-.

Is this a bug?

I'm using 4.00 tho

Thanks in advance!!

You should really think about updating to 4.7 or 4.8 beta 2. Also, as for your replay, you could just open the .rpl file in a text editor and change the names around from uke to Karstnator and vice versa. That will make it so it loads your customs as your opponent and your open load on you and therefore you will be doing the decap.
