Nexus Clash

Seen on The Necronomicorn (https://nexusclash.com/clash.php?op=character&id=9344)

After a respawn, I found a tile with a corpse on it and went to summon a skeleton (I had 33 MP at the time, so more than enough). The game threw an error message saying: "You lack the requisite MP or skills to summon that pet!" I tried a wight instead, and that summoned normally. It's just the skeletons giving me problems.

I went and found a different tile with a corpse on it, and the summon worked. So in light of that, the bug was noticed at 10,35 in Cordillera.

I attempted to reproduce this on devserver, both in general and at that location, and could not.
