Does anyone know if it is possible in some way to change the rules of some competition in a game in play with FMRTE?

not possible using an in game editor and I know from your post over on sortitoutsi you want to change away goals rules https://sortitoutsi.net/content/58597/change-the-rules-in-a-game-in-play#comment_644092

 

has to be done pre game

Devs have tried editing rules like this previously but it makes the game+ or app unstable and crash

 

so only way is using the pre game editor

I have changed the title to better reflect the question as I know English isnt your first language👍

 

cheers

will close this as answer given

I explain here how to do it pre game

 

Changing away goals rules in UEFA comps

 

Read this thread where it is explained https://sortitoutsi.net/content/58465/uefa-away-goals-rule#comment_640086 

 

its again easy to do but you have to remove it for each KO round in every UEFA comp- dont forget the pre group stage rounds as some may well have 2 rounds being played and match day 2 rules with away goal rules added as default

 

NB if a competition has more than one set of rules set up by SI covering current season and then a different start year eg 2021

I would edit both sets of rules to be sure
