Single Player Manticore, no timer - change or bug?

[BrankMeister]

Yesterday (20th Aug 2017) I went in to confront the Alpha Manticore to see how hard it really was in Single Player. I brought 7 low level Wyverns, a Yutyrannus and a Daedon fully expecting not to come back.

I was surprised to observe that:

• There was no timer during the boss fight. It ended in me running out of ammo and rockets and just giving up (100k health left on the beast)
• My dinos got knocked out regularly but only 1 of them was actually killed by the Manticore. The others by death worms when KO on the ground
• All Dinos woke up several times to have another go
• When I cheated 'KILL' 4 of my dinos made it back with me; 3 of them were still knocked out and took a few minutes to wake up!
• I was sitting on the Daedon most of the time and the Manticore could not, or would not hit me (good old piggy!)
• Primitive equipment: 1 rocket 600HP off, 1 sniper bullet 100HP, 1 assault rifle 20HP

So my questions:

• Is the lack of a timer intentional for Single Player now? This means that with enough ammo the boss becomes very feasible (a LOT of ammo)
• Unconscious dinos used to get killed, is this a change for SP, or is this for MP as well?
• I read that Wyverns couldn't go into the Manticore arena any more; is that a difference between SP and MP?

I had fun with this and under these conditions I think I could stand a chance to actually beat the beast with a better set of dinos, the timer was always my main concern when going at it solo.

The timer was removed for SP, and as far as I know, wyverns have always been able to go into the Manticore arena.

Thanks; I thought so too, but recently read some comments about all flyers having been removed from the Manticore arena.
Stunned creatures coming back alive was new to me too.

Knocked out creatures USED to not tp back now they do.
