Hi @ufoscout, thanks for reaching out.
This seems to be related to the fact that version 2.0 defaults to an application subnet to more closely resemble the mainnet. Version 1.0 was using a system subnet by default.
On mainnet, your calls would likely also fail with that error message; may I ask why you’re executing these calls?
One way you can circumvent this is to call pic.advance_time(X minutes), execute a few rounds with pic.tick() and retry.
Does this help?
