Freshly installed D8 (8.2.0-dev as required by dev code)

Enabled Accounting Core, Balance Limits
Registered a new user.
Trying to set its limits (/wallet/2/limits), getting "The website encountered an unexpected error. Please try again later."

Website log contains:

Looks like CurrencyInterface is not taken from Drupal\mcapi\Entity namespace.

Temporary solution I used:

diff --git a/modules/limits/src/WalletLimiter.php b/modules/limits/src/WalletLimiter.php
index a696580..ceb7722 100644
--- a/modules/limits/src/WalletLimiter.php
+++ b/modules/limits/src/WalletLimiter.php
@@ -170,7 +170,7 @@ class WalletLimiter {
    * @return array
    *   The min and max limits.
    */
-  public function defaults(CurrencyInterface $currency) {
+  public function defaults(\Drupal\mcapi\Entity\CurrencyInterface $currency) {
     return \Drupal::service('plugin.manager.mcapi_limits')
       ->createInstanceCurrency($currency)
       ->getLimits($this->wallet);

Need to make up namespaces.
