Cura supports issues. PLA warp and bubbles of plastic

PLA Bubbles
“PLA can absorb moisture from the air. When it is heated this moisture can turn to steam bubbles which with certain hot end (extruder head) designs can interfere with printing. The symptom is that when the extruder motor stops the PLA kept coming out. When the stepper starts again there is a significant delay. Occasionally the tip may blow a bubble with a tiny puff of what looked like steam.

Warping at the bottom. (ABS, I am using PLA)
It only seems to be doing it to objects and take some time. Though the bottom layers print fine initially, the bottom seems to slowly warp over time as the printer works on higher layers.
May be inaccurate temp readings.
