Sorry, got currently no time to check this
Maybe in the future.

Edit:
Checked the code at a glance, try this:

--New English
 -- Add Wayshrines
    local temp = {}
    for cityName, cityData in pairs(languageTable.defaultEmotesByCity) do
        local cityWayshrine = string.format(GetString(SI_DEATH_PROMPT_WAYSHRINE) .. " %s", cityName)
        temp[cityName] = languageTable.defaultEmotesByCity[cityName]
        temp[cityWayshrine] = languageTable.defaultEmotesByCity[cityName]
    end
    languageTable.defaultEmotesByCity = temp
 
 
--new German
-- Add Wayshrines
    local tempDe
    for cityName, cityData in pairs(languageTable.defaultEmotesByCity) do
        local cityWayshrine = string.format(GetString(SI_DEATH_PROMPT_WAYSHRINE) .. " %s", cityName)
        tempDe[cityName] = languageTable.defaultEmotesByCity[cityName]
        tempDe[cityWayshrine] = languageTable.defaultEmotesByCity[cityName]
    end
    languageTable.defaultEmotesByCity = tempDe
