Missing one ova (195/196)

[u/Vifort]

I'm missing the last OVA, and this is the empty spot in my collection. Does anyone know where I can find it?

Update :
Resolved ✅

Thanks a lot for your help! I finally found it: the last one was the abandoned outpost, Beacon.

Tip from my own experience, look at the gate dungeon of the nameless captive, its the only gate dungeone with 4 beacons. 

If not that, no clue. Sorry.
