It’ll cause more zits and the like, more stringing, don’t know that’d 100% cause the issue but certainly won’t help.

I just did a round of nylon last week which is also super hygroscopic, bag’s like at most 8 months old but seal was intact. Even printing out of a drybox with fresh desiccant I noticed more stringing and occasional blobs + nozzle buildup over the few days (Was redoing my hotend so I inspected it, no sign of nozzle leaking), can definitely make overhangs worse.
