Client#readStringUntil only ever returns first element

[DarkEyeDragon]

When testing the following code i came to the conclusion that only ever one element is returned for Client#readStringUntil

client.readByteAlways(opCode -> {
    if (opCode == 2) {
        List<String> tempWarps = new ArrayList<>();
        client.readString(s -> {
            client.readInt(warpSize -> {
                AtomicInteger count = new AtomicInteger(0);
               //this part
                client.readStringUntil(s1 -> {
                    tempWarps.add(s1);
                    return warpSize < count.getAndIncrement();
                });
            });
            serverWarps.put(s, tempWarps);
        });
    }
});

it seems to ignore the return value. if i swap < for > the result is the same.

I also tried using client.readStringAlways but this messes up when new packets are received as they're still getting handled in the readStringAlways
