I had it in my house for probably 3-4 years haha. I believe I opened up the SD compartment to look in there at some point, but don't recall it "not" sealing properly if that makes any sense.
Ah, OK, well maybe just try bringing it indoors, open it up and let it dry for a few days at least, then re-assemble and possibly try sealing all case joints with silicone or similar. Might be worth checking the rubber gaskets if visible, I have known these get crushed or misaligned from factory. It is a very annoying problem though!
