What did you do?
Tried to upgrade a normal quality infinity storage chest to a legendary quality

What happened?
Upgrade planners don't allow infinity chests in the "from" position.

What did you expect to happen instead? It might be obvious to you, but do it anyway!
They are allowed in from.

Does it happen always, once, or sometimes?
Always.

If you can reproduce the issue, provide the exact steps!

0. Turn infinity chests on using Editor Extensions
1. Open an upgrade planner
2. Try to put any infinity chest in the "from" position (it works in "to")

This might be a mod bug, but since these items are hidden in the base game, I'm guessing it's a game bug.

Thanks for the report however this is up to the mod to configure if they want to allow this. The engine does not restrict the entity type from being in the upgrade planner. The requirements for being on the from side are the same as any other entity and up to the mod to allow if it wants.
