How to handle cumulative answers?

Hey @mateuswetah

Basically, all handlers in Wizard flow can be called in any time, even after bot app restart.
I suppose in this case you can try to use session for storing intermediate values.
But you need to clear session values after all, or even better using flow.session, cause this session will automatically cleared on scene change:

const addItemToListScene = new WizardScene('addItemToListScene',
(ctx) => {

       const existingListMenu = Extra
		.markdown()
		.markup((m) => {
			var existingLists = [];
			for (list in ctx.session.lists) {
				existingLists.push(m.callbackButton(list))
			}
			return m.keyboard(existingLists).oneTime().resize()
		})

	ctx.reply('Ok. To which list would you like o add an item?', existingListMenu, Extra.markup(Markup.forceReply()))
	ctx.flow.wizard.next();
},
(ctx) => {
	 ctx.flow.session.listName = ctx.message.text
	 ctx.reply('Give me the name of the item you wish to add to list ' + listName, Extra.markup(Markup.forceReply()))
 	 ctx.flow.wizard.next();
},
(ctx) => {
	const item = ctx.message.text
	ctx.session.lists[ctx.flow.session.listName].push(item)
	ctx.reply(item + ' added!'))
	ctx.flow.leave()
})
