the text for spy protection says:
"Provides 50 ticks of spy alertness. Any hostile spy trying to conduct an operation with infiltration lower than"

lower than what? So if a spy wants to preform an operation with requiring 6 infiltration and spy protection is activated just before the action is taken, how many infiltration points will it take to perform the action, assuming the target has no spy? what if the target does have a spy with say 20 infiltration point?

If u put spy protection (50 ticks) u are just protected for 50 ticks, if a spy got lower ticks than 50, the spy is killed, now, if the spy gots more than 50 ticks of infiltration, the spy protection doesn't works.
hope that helps!

Thank you for reporting the bug, I'll complete it:
"Provides 50 ticks of spy alertness. Any hostile spy trying to conduct an operation with infiltration lower than your spy alertness will get captured"

Or something like that, I'll try to have it fixed

Thanks I think that answers my question
