I'm about to upgrade my spell factory to level 4, but I want to lessen the impact of being without spells for 5 days (and 2 full CW). I have spells cooking in there now, but if I start the upgrade before the spells are done cooking, will they finish during the upgrade or will I have to wait?
Basically, should I wait two hours to start the upgrade or am I ok to do it now?
