FNG question about double skills

[pyropappy]

I am level 50, if I buy double skill now do I get to claim the second skill lost from level 38 to now, or will I only get second as I level up from this point?

[AxleBlaze9]

u will not lose any skills. if u activate double skills u will get another 50 points according to u r lvl 50 which u can invest in skills

[Nubito]

new skill tree will empty with full point skill for your level
your old skill tree will not change
