Unhandled Exception

[Yanik39]

Hello,

I am using Hearth Ranger and Silverfish latest versions on windows 10 x64.
Everything was ok since months but for last few days i get "Unhandled Exception" error few times.

At Silver.exe screen i get this error text at the end of normal calculations;

deep 4 len 171 dones 5
cut to len 77
ailoop
deep 5 len 76 dones 6
cut to len 31
ailoop
deep 6 len 7 dones 7
cut to len 7
