When in Survival the potion effect "Health Boost" is very buggy for the fact that every once and a good while it cuts you back down to 20 hearts and it deals damage to you so that instead of having 24 hit points after eating a golden apple you every about 24 seconds your health gets knocked back down to 20 points and it has to regenerate again. While having this effect in creative it still takes place and you get hurt and return back to 20 hit points which could be a real problem for adventure maps. Example: (Not Too Important) If your in an adventure map with health boost level 9 (which is 3 rows of hearts) it would every 24 seconds knock you back down which is really going to be a problem because it will kill the custom health in the custom maps game play. Thank you.
