Script not working on windows client

[dalukas 0]

Hi,

I'm having a kind of a weird problem. My script I wrote runs perfectly on my dreambotclient on Mac OS but when I run the same script on a windows machine.
It act's rather strange, all of a sudden can't detect what's in my inventory etc.
Script runs flawlessly on Mac tho

if (FallyBank.contains(myself) && !inv.contains("Rune essence")) {
            //open bank and grab them 
            log("banking");
            dobanking();
}

private void dobanking() {
        log("Checking To See If Banking Needed");
        NPC banker = getNpcs().closest(npc -> npc != null && npc.hasAction("Bank"));
        if (banker != null && banker.interact("Bank")) {
            if (sleepUntil(() -> getBank().isOpen(), 9000)) {
                getBank().withdraw("Rune essence",27);
                if (sleepUntil(() -> getInventory().contains("Rune essence"), 8000)) {
                    if (getBank().close()) {
                        sleepUntil(() -> !getBank().isOpen(), 8000);
                    }
                }
            }
        }
    }

These are the functions it keeps on banking over and over again. trying to find the banker through the banking screen.
