Fixes GTNewHorizons/GT-New-Horizons-Modpack#24872
updateGliders() iterates over gliderMap.entrySet() while the map can be modified during the client tick (thaumcraft hungry nodes as a example), causing a java.util.ConcurrentModificationException, The fix replaces the iteration with a snapshot copy (new ArrayList<>(gliderMap.entrySet())) to separate iteration from concurrent modifications during rendering with failsafes.
