Blue Lotus open beta bugs here:

[The_White_Knight]

so how do you exactly get rid of the monks?

Take a back-up of descr_strat.txt in Rome - Total War/Data/World/maps/campaign/imperial_campaign

Search for

faction	romans_julii, comfortable caesar
;superfaction romans_senate
denari	10000
settlement
{
	level large_town
	region Padma_Provence
...

And remove everything starting with the bolded "settlement" (see above) up until you reach

faction	romans_brutii, balanced stalin
;superfaction romans_senate
denari	5000

The result should look like this

faction	romans_julii, comfortable caesar
;superfaction romans_senate
denari	10000


faction	romans_brutii, balanced stalin
;superfaction romans_senate
denari	5000

And gone are those random CTD's (not all of them though).
