how do you got it to work ?
i enable the option but none of my developments speeds up or something. It stays same .
hmm I didn't really do anything specific, just enabled mega unlocker and rapid development and started crafting, however it doesn't affect already building items if thats what you mean
You are the only person requesting this and this requires additional time and resources to add (and LOE for it is unknown). Time is better spent on other trainers so you really need to submit why Caliber should shift his focus from other issues to this one request.
