Nasty bug in the preview: packaging fails if I create a math expression and change the pin types from float to int.
LogBlueprint:Error: Broken Node: K2Node_Tunnel /Game/Blueprints/Helpers/PickupStatusChanger.PickupStatusChanger:EventGraph.K2Node_MathExpression_154.MathExpression.K2Node_Tunnel_1377 keeps removed/invalid pin: EdGraphPin /Game/Blueprints/Helpers/PickupStatusChanger.PickupStatusChanger:EventGraph.K2Node_MathExpression_154.MathExpression.K2Node_Tunnel_1377.EdGraphPin_39110. Try refresh all nodes.
I also had to manually re-create all my math expressions, but the ones where I use int instead of float fail to package every time. Oddly, the game runs fine in PIE and even mobile preview. I just can’t package it for some reason. I’m also getting LOTS of warnings about deprecated outers.
