In the latest version, when running a custom script for a DNS-01 challenge, during validation steps I receive an error message that authorization is invalid... it appears that this is due to validation retry is not occurring.

Previous version output (working):

[myhost.com] Authorizing using dns-01 validation (DnsScript)
Script \UNCPATH\Create-TXT.ps1 starting with parameters create myhost.com _acme-challenge.myhost.com "S4DgbiJJ3Myz8pzMwLNnz9wsCsw9Os2RqpFDtbr6dyg"
Script finished

[myhost.com] [#.#.#.2] No TXT records found

[myhost.com] Preliminary validation failed on all nameservers
[myhost.com] Will retry in 30 seconds (retry 1/10)...
[myhost.com] Preliminary validation succeeded

Current version output (failing):

[myhost.com] Authorizing using dns-01 validation (DnsScript)
Script \UNCPATH\Create-TXT.ps1 starting with parameters create myhost.com _acme-challenge.myhost.com ""
Script finished

[myhost.com] Deactivating pending authorization

Renewal for [Manual] myhost.com failed, will retry on next run
Validation failed

Expected behavior
Validation retry should occur before failure

Additional Info
While testing, if I add a 20 second pause in my Create-TXT.ps1 script the validation does succeed as it has in the past.
