Fog cloud + bonus action (hide) makes you invincible, needs fix

[Nuglet]

using an action and bonus action to fog cloud then hide and then using an action and then hiding on subsequent turns makes you and your party functionally invincible. The ai just does nothing. Now i know some one will inevitably say just don't do it if it is overpowered, but this is a normal combo in dnd 5e. the ai needs to be able to try to make a perception check at least because even melee enemies just end up stand on the outskirts of the cloud or do nothing at all. Additionally having both disengage and hide as bonus action is too strong on all classes and devalues the rogue who is supposed to get these as his level 2 feature. Hope someone sees this so the Ai gets an updated, different bonus actions replace hide/disengage which should become full actions. P.S. this game is amazing for being early access, really hope these gets fixed upon full release.
