So it seems to me that using meteorite ichor for oort amalgam is quite an unpopular way of fueling portals, as it is a bit of a grueling task to have your portals fueled exclusively with oort amalgam (since this is the only way the game allows it- oort shard or oort amalgam)
Because of this, all the ichor I get just sits on a shelf unused. Why not make it able to stack in a smart stack with oort shards in the fuel slot, so that one can make use of both ichor and oort shards at the same time, without having to only put one or the other in?
If it were this way, I would definitely be putting my ichor to use, so that I could extend portal fueling times beyond the ability of oort shards alone.
