On a recent playthrough I noticed that I went through several missions in a row without getting any elerium. Powersupplies were intact, so I did some googling to try and figure out what was going on and found that (in vanilla X-Com) sometimes elerium isn't spawned because there's a limit to how many items could be spawned on the battlescape, and elerium is given the lowest priority. I pulled some extra ammo from the Skyranger, and the next mission collected elerium as normal. Is this item limit still present in Open? If so, since it seems to be mostly a technical issue, not a balance one, could it be removed? Most of the other item limits and related bugs have been removed/reworked, so it seems slightly odd to me that this one is still present.
