Changes Proposed

new CreatureEvent onConnectionRestoration
Handle switching game client without logout which is currently impossible.
example: call login CreatureEvent that will set bless icon status, after switching the client the icon will not be updated

local blessStatusLogin = CreatureEvent("blessStatusLogin")
function blessStatusLogin.onLogin(player)
	local blessCount = 0
	for b = 1, 5 do
		if player:hasBlessing(b) then
			blessCount = blessCount + 1
		end
	end

	local msg = NetworkMessage()
	msg:addByte(0x9C);
	if blessCount == 0 then
		msg:addU16(0)
		msg:addByte(1)
		msg:sendToPlayer(player)
		msg:delete()
		return true
	end

	local bits = bit.bor(4, 8, 16, 32, 64)
	if blessCount == 4 then
		msg:addU16(2)
		msg:addByte(2)
	elseif blessCount == 5 then
		msg:addU16(255)
		msg:addByte(3)
	end
	msg:sendToPlayer(player)
	msg:delete()
	return true
end
blessStatusLogin:register()

-- solution

local ce = CreatureEvent("blessStatusConnectionRestoration")
function ce.onConnectionRestoration(player)
	print("blessStatusConnectionRestoration")
	local blessCount = 0
	for b = 1, 5 do
		if player:hasBlessing(b) then
			blessCount = blessCount + 1
		end
	end

	local msg = NetworkMessage()
	msg:addByte(0x9C);
	if blessCount == 0 then
		msg:addU16(0)
		msg:addByte(1)
		msg:sendToPlayer(player)
		msg:delete()
		return true
	end

	local bits = bit.bor(4, 8, 16, 32, 64)
	if blessCount == 4 then
		msg:addU16(2)
		msg:addByte(2)
	elseif blessCount == 5 then
		msg:addU16(255)
		msg:addByte(3)
	end
	msg:sendToPlayer(player)
	msg:delete()
	return true
end
ce:register()

probably to remove and change to use if (thisPtr->player) instead
