Hey guys, I've been trying to network a PUN grenade GameObject across the network. It even seems to work, since the players in my Photon Room take damage and die from it all the time.
However, I sometimes get the Exception mentioned in the title, which is coming from the PunObjectPool. I've made sure that my PUN grenade prefab has been added to the PunObjectPool in my scene, so I'm not sure why I'm getting this error. Hope I can get some insights here.

Are you able to reproduce this in the demo scene? I remember seeing a similar error before but thought that it was fixed.

In the PUN demo scene I get this exception when I pick up a grenade:

Are you running the latest version? That error looks similar to one that was fixed earlier. What grenade did you pickup?
 
Ah. it looks like there are some frag grenade pickups that have an empty ItemDefinition in the Item Pickup component. If you remove the empty references that error will go away.

Okay now I've made sure that all the grenades have the ItemDefinition, but then I get this error:

I was able to reproduce that error. It looks like there are some others as well related to grenade throwing. I'll get this fixed for the next update.
