Oh, I feel your pain! High humidity speeds up cyanoacrylate curing drastically. If your glue is normally a 1-2 second drying time, in 65% humidity it’s probably flash-curing in under half a second. That's why you're getting weak bonds.
Before buying a new glue, try dialing down your room humidity if you can (a dehumidifier saved my life last summer). Also, make sure you're refreshing your glue drop every 15 minutes max instead of 20-30. If that still doesn't work, then yeah, definitely grab a glue formulated for higher humidity/slower cure times."
