I started on the beta server shortly before the end of the winter event - and therefore I have a confectionary and a large confectionary, both from the Bronze age. Does it make sense to keep them (hoping to get a chance to improve them in a later event) or is it better to delete them and replace them with HMA buildings? (I will reach LMA in a few days)
keep it
There should have events, in future, that u can trade it to updated 1
1st of all, u must have the item
e.g. u have a brozne age confectionary
When a event come ( e.g winter event)
in 1 of the event, they will give u a confectionary of your current age (e.g. Colonical Age )
if u have already get 1, then u will exchange your 1 to a large confectionary of Colonical Age
In that case, u get your confectionary updated ( from bronze age to current age ) and also have a larger collection
The above is just a example, no one can gurantee game developer will give a chance to replace your confectionary in winter event, it may happen in other evetns
but large confectionary is already a existing items in the game and
the process of replace old items are already happen in some events
