Some techniques are missing

[priamai]

Describe the bug
I discovered randomly that some techniques are missing.

To Reproduce
Steps to reproduce the behavior:

from pyattck import Attck

attack = Attck(
    data_path='./pyattck/data',
    enterprise_attck_json="https://raw.githubusercontent.com/mitre/cti/master/enterprise-attack/enterprise-attack.json",
    ics_attck_json="https://raw.githubusercontent.com/mitre-attack/attack-stix-data/master/ics-attack/ics-attack.json"
)

attck_db = {}

for technique in attack.enterprise.techniques:
    if technique.id == "T0885":
        print(technique)
    #print(technique.id)
    #print(technique.name)
    #print(technique.external_references[0].external_id)
        
    tactic = technique.external_references[0].external_id
    
    phases = technique.kill_chain_phases
    attck_db[tactic] = (technique.name,[phase.phase_name for phase in phases])
    
for technique in attack.ics.techniques:
    if technique.id == "T0885":
        print(technique)
    #print(technique.id)
    #print(technique.name)
    #print(technique.external_references[0].external_id)
        
    tactic = technique.external_references[0].external_id
    
    phases = technique.kill_chain_phases
    attck_db[tactic] = (technique.name,[phase.phase_name for phase in phases])

Expected behavior

It should lead to:

https://attack.mitre.org/techniques/T0885/

instead the technique is not found.

Getting this error:
