I sent the ticket to the support team but anyway I'd like to write also here.
1) I think you can add periphery updates (e.g. upgrades of Face of Ancient and Gate of the Sun God ) earlier and you won't lose anything. More then, you can add anything more seldom instead of them on the 4th round.
2) The main part of my offer, is about upgrades of Terrace Farm, Fountain of Youth and Sacred Sky Watch which gamers can get on the points 58 and 62. But there's a 50% chance to win 30 and 35 goods. For what? I think you can delete goods from there and keep just those upgrades variants with 50% each of them.
3) We can win Terrace Farm, Fountain of Youth and Sacred Sky Watch earlier in the Guild Expedition by collection Rare Relics. Why can't you create a special type of Relics for their upgrades or add these options into Rare Relics?! It is logical: if we can win the prizes we should also have the chance to win upgrades for them by collecting Relics. You can create, as I've just written, a special relic with the same chance as, for example, Rare Relic. Again: you won't lose anything and gamers will get an additional motivation for playing the Guild Expedition because now it is truly an annoying thing when you reach points 58 and 62 and get 30 and 35 goods.
