Probably "not-a-bug", but more of a ambiguity issue that affects the (beta) player experience. Items in the Logit Store are sometimes only available in the Beta version, and as such, if a player uses logits to purchase them, the item is lost when the players switches (or is involuntarily switched) to public, resulting in lost logits.
Either make beta-only store items have a cost of 0 resources, and/or mark/flag beta-only items so that players know the item will disappear.
