Submitting a menu form kicks the player

[AndreasHGK]

Whenever I create and send my menu form to the player and they click a button, they will get kicked with the following message DEBU[0015] failed processing packet from [ip]:65076 (AndreasHGK): *packet.ModalFormResponse: no form with ID 1 currently opened

I added a debug line fmt.Println(pk.FormID) in ModalFormResponseHandler and it seems like the packet is somehow being handled twice

I added all these in the ModalFormResponseHandler:

	fmt.Println(pk.FormID)
	fmt.Println(pk.ResponseData)
	var index uint
	err := json.Unmarshal(pk.ResponseData, &index)
	fmt.Println(index)
	fmt.Println(err)

and it returned this:

1
[49 49 10]
11 //this is the actual button i pressed
<nil>

1
[110 117 108 108 10]
0
<nil>

Putting a fmt.Println(bytes.Equal(pk.ResponseData, nullBytes)), it seems like the second packet returns null
