Experiencing inconsistent enemy spawns (Solo)

[halex98]

So far my overall experience of Fortuna has been positive and enjoyable. I have been playing solo so I have no clue if this is an actual issue or not when it comes to having a team but every once in a while during bounties I'll experience either an overwhelming amount of enemy's spawning non stop even on a low alert level, or there will be no enemy's around anywhere when the bounty requires me to kill them. Is this just Warframe having spawn problems with solo play or does this issue arise when in groups as well.
