better to ';' lines with positions for all setupped plagues in d_events (without deleting date line, that will leave plague event, but it wouldnt have any effects just notification)

';' places in the beginning of the code line, meaning it wont be used (just a way to disable code without deleting it, so can go back quickly)

Code:
event	plague		plague_in_italy
date	144 summer
;position	96, 82
;position	95, 71
;position	102, 68
;position	114, 63
like this.
d_disasters should remove random plagues i think..

new campaign should be necessary in that case as old descr_events used (but i'm not expert in when you need it or not).
