Why is the simulation incorrect?

is it a world with morale ? if so update you sim if u use the native sim try a different one .if you wait to long the health increase causes differences when in doubt i hit refresh on the sim 5-10 times before launching

The accuracy of third party sims is never certain. The in-game one should be accurate however it has always been the case that a sim is an indication of outcome only. Sometimes, if you sim the same base with the same attack configuration you get different results. I can't remember the explanation given at the time this was last discussed a long time ago, but there was one.

As indicated above, simulating attacks always only considers the status of the base from that very moment. In some cases, the regeneration from one moment to another can change the outcome because of just that one unit having a sliver of health gained, thus changing the course of battle.

In some cases I noticed the opposite. A simulation on a nearly destroyed base would result not in a destruction, a moment later, it will. Because of how the course of the battle changes. Odd for sure but not a bug.

thanks but this needs to be made clear really as it does'nt say 'approx sim' so its taken as the actual sim, not everyone knows this and it is a problem, iv'e even watched the sim prior to the attack and it kills the base then when pressed it does not kill, if there is something for a more accurate sim or a script could you post the link please

I doubt there is a more accurate sim. How would the simulator know how far in the future you would like to attack and what the status of your army will be. Best bet would be to attack right after a successful sim. That's the only way I see to reduce the chance of errors.

This is only an issue with worlds with that stupid morale reduction BS.
Sim a base without that morale reduction in play and you will get a perfect 100% accurate Sim.
Sim a base with morale reduction and the Sim will vary wildly.

Obviously what has been said about the base regeneration also applies, but if there is no morale reduction, the Sim will give you a perfectly accurate result for a run launched at the exact moment you simulated. Every second you spend simming again, the base will regenerate and the results will change but that is expected.

I think the morale reduction is a percentage and is randomly generated on each attack run. So everytime you simulate a random number somewhere in the range of the stated value is applied to your units.
Or maybe it's generated for each unit in your attack or each forgotten unit? That seems too complicated though.

Either way I hate morale reduction.
Thank you for listening to my rant :p

i think the morale on wrath 25 is just crazy, its a slow painful grind of a server, also the morale is higher there than any server i have seen before and the layouts are shocking, was this how it is meant to be?

also i appreciate the replies

thanks
