I've tried
1) activating unlimited bytes
2) collecting in-world research points then activating the option
3) activating the option then collecting in-world research points
none will let me have unlimited research - on version 0.7.0.0 you had to collect then activate the option for it to work - this time it doesn't seem to work no matter the order in which you choose the options
did you actually try using bytes after activating the option?
